How would Italy becoming a major power impact its diaspora population?

Just asking because to achieve what you want in the time-frame you mentioned you'd need Italy to have quite a few lucky breaks more than what could reasonably be expected within that same time-frame.
Could Italy weather the world wars or just the second one? Wouldn’t that put them in a good position especially if they played the conflicts into their hands?

Getting out of the World Wars relatively unscathed would require Italy to already have stable possession of both Trentino-Alto Adige, Istria and Dalmatia, the acquisition of which was Italy's endgame for WW1 and failure to achieve it completely at Versailles a big part of the reason Italy was so eager to enter WW2, and that would have required Italy to already be powerful enough to keep Austria out of the Adriatic back in the XVIII century, making it more likely for the country to pull a Switzerland during both World Wars, unless butterflies conspired to drag it in regardless.

Couldn’t Italy go into ww1 and have Mussolini rise as otl but stay neutral in ww2 and go do what they want when all the powers are distracted by the war. They play both sides during ww2 for its own gains and maybe even join late once the allies start pushing the Germans from both fronts. Maybe Italy even carved out its own bloc during the war in the Latin nations and the Balkans. Even if both the eastern and western bloc after the war see Italy as a rogue state that abused ww2 for its own gains they are probably too drain at least mentally to fight or push against Italy too hard especially with Italy avoiding the direct destruction of ww2. The US could also see Italy and its allies as a good way at containing the communist and USSR even if they don’t trust them fully. Fascist Bloc with Italy as the head? They aren’t as strong as the west or eastern bloc to start off with but they can hold their own. They rally undemocratic right wing regimes to its bloc? They also have more cordial relations with the west then the eastern bloc. They are more treated like modern Russia or China by the democratic western nations? Basically non-allies don’t trust them but they will work with them when they find it needed?

Full neutrality, much less what you're proposing, wasn't really an option for Mussolini when the war started. At that point, he was in too deep with Hitler to expect anything else but a German occupation of Italy if he got cold feet at the last moment. He had a valid reason, the state the army was in, for Italy to stay on the bench until 1942, but ended up shooting himself in the foot by entering the fray in 1940 because back then it seemed Germany was going to have won the war by the time Italy was ready to fight it.

Wouldn’t that depend on how relations develop between the two? Also why would Germany be set on Italy entering the war? It just open up another front and drained troops. Germany would have more men to use east and more men defending France. Italy could be officially neutral but in reality they are selling resources to the Germans. Germany invading Italy that is sympathetic or at least cordial with them would be very bold and insane on Hitler’s part especially when they are fighting everyone else. Even if they are successful that would stretch the German army to extreme limits.

That's very true, I was just pointing out what prevented any other outcome than what happened in OTL.

It wasn't so much Germany as a country, but Hitler himself that considered it a foregone conclusion, given the talk Mussolini talked. Since the two were allies at the time, the Fuhrer would have very likely considered Italy adopting a policy of full neutrality during the war a betrayal and a surrender rolled into one.

Also true, I wasn't saying that something along those lines would happen with any degree of probability, at least as long as Germany had other cats to skin.

Could that play into Italy favor if Hitler invades Italy later into the war and right before the USSR and allies start pushing from both sides? Hitler racist views and increasing insanity makes him think Italy will be a easy and quick conquest but the Germans are over stretched and already fighting the war on multiple fronts. Mussolini and most Italians get really pissed at Hitler and the Nazis by what they consider a betrayal and unjustified aggression by a nation that was supposed to be at least cordial with them. Mussolini and the fascist now rally the Italian population who are much more committed to the war due to the nature of how they entered it and are better prepared for it. Italy due to having at least until 42 to build up its military and make it competent is able to stop the German invasion. The deepest the Germans push is maybe the outreaches of Venice before being pushed back. The Italians are actually now able to push into Austria and maybe south Germany before much of the allies or USSR can. This isn’t due to Italy being a top tier or great military power but more due to the fact the southern front is the least defended since more troops are either in Eastern Europe or France.

Maybe Italy is also much more willing to work with right wing opponents of Hitler and be more lenient with the Germans then the other powers. A lot of the Wehrmacht and old guard will probably be upset with Hitler invading a fascist nation they are trading with especially with the war becoming increasingly hopeless for them. This leads to massive surrender of German troops to invading Italian forces who probably prefer surrendering to them over the USSR or even the allies. Basically, Mussolini orders SS and Nazis elites to be executed but the Wehrmacht and Prussian Junker types are given very lenient treatment especially when Italy depicts them as men “just following orders” and puts all war crime blames on the SS and Nazis elites. German generals and scientist can easily be recruited by Italy. The Wehrmacht and people like Rommel are fascist but they are fascist more like the Italians or traditional fascist then the Nazis. Rommel and Wehrmacht want a Greater Reich and have no problem with killing opponents but they aren’t the extreme racial purist like Himmler and the SS. Mussolini would target the old guard and fascist who oppose Nazism for support. People who are strict on Aryan blood(Italian fascism values culture over blood especially among Europeans and hated how they looked down at the non-Germanic Italians) and Neo-Pagans(often extreme racial purist too who looked down at Mediterraneans) are probably purged by the Italians with the help of local fascist support. Those two groups were usually the most extremist Nazis. This could help Italian advancement through the Reich go much faster especially if the Italians are willing to immediately rearm the Wehrmacht and create a fascist puppet in South Germany/Austria from the get go that is dominated by the Wehrmacht and a good mix of the old guard and Junkers fleeing from the east. If Italy is giving Germans food, shelter, and working with them when the allies and USSR are not they are going to have a much more welcoming and easier time in Germany. Imagine the possible responses Italy could get from German citizens if they do this while the allies do pillow bombing and USSR is doing what it did. Unless Italy faces heavy German occupation they are likely to be more lenient and cooperative with Germans especially with the fascist and right wing. Italy could have the Wehrmacht have mock trials for Nazis elites and SS before quickly executing them. That would be a useful propaganda tool for Italy.

Furthermore, Hitler invasion of Italy would likely turn many fascist leaning nations against the Nazis even if they don’t officially join the war. Spain probably supports Italy indirectly at first and maybe jumps in completely once German defeat looks certain. How is neutral fascist nations like Spain supposed to take a invasion of Italy by Germany? Germany would have invaded a fellow fascist nations, technically the original fascist, who worked with Germany in the past and who was currently trading with them because Italy didn’t follow Hitler’s demands to the word. This could create a situation where fascism and Nazism start looking at each other as different groups. Nazism start depicting themselves as a completely separate and unique German ideology while depicting fascist as a “reactionary and devious mix race people”. Italy could turn Spain and Romania away from the German side towards theirs if planned well enough especially if butterflies makes Romania neutral before Italy enters the war. Invading Italy would likely turn Nazis remaining leaning and sympathetic nations against them. You can only go after so many people before everyone starts looking at you as a straight up bully. Could some of these points play out or work?
 
That's a very well thought out strategy, all the things you proposed are indeed plausible. Also, Italy keeping out of the war until it gets dragged in by force would very likely mean much lessened ethnic tensions in the Balkans later, if the Germans keep their focus on the USSR. ITTL Italy was probably caught flat footed by Germany while they were about to try their luck and snatch Dalmatia from Yugoslavia.
