Yes! I'll give my thoughts at lunch.
-In the early days, there were exactly 2 Continental Associations that mattered: Europe and South America. I think the choices you've made for hosts are all pretty reasonable, except that IOTL by 1962 they had settled in on a very firm "rotational" policy if alternating hosts between Europe and the Americas.
In a no WWs world, I would imagine that Europe would remain more powerful and relevant, and so this rotational policy might start later, but at some point between say 1962 and 1978 you're going to be beginning the rotational policy, I would imagine.
That being said, other than a vague feeling of being more rotational, I'm not actually going to take objections with any of your hosting choices. You and I probably wouldnt come up with the exact same list, but 1) doesnt mean I'm right and 2) it's your world anyway.
Also, I once wrote an award-winning essay (as a 14 year old, so not like a real award) which went into great depths to explain that der Mannschaft (ze German national team) became as powerful as they did only in the wake of (and as a result of) demilitarization of society.
I went on to argue that football was a replacement for war; and that the countries with the best football teams are ones that "underinvest" in their military, so to speak. (And also the inverse).
I dont stand behind this sentiment nearly as much as I used to, but I do think no world wars ironically delays German demilitarization of priorities and society; and as such, the Danubian Federation will be the powerhouse of Europe, at least until around the late 1970s or 1980s, at which point I'd imagine Germany is ascendant.
I also suspect (kind of counter to what I just wrote) that a no wars Japan is one that 1) is trying to prove itself equal to other powers in every way and 2) is more British influenced and less American influence - so Japan probably adopts football as a popular sport earlier.
The above is just general no wars thoughts; I'll re-read the thread for more insights to what you've written specifically
Here's a rough idea of how I might start out:
Year Host Winner Finalist
1930 Uruguay URUGUAY Argentina
1934 Italy ITALY Danubia
1938 France DANUBIA Italy
Ok so this is my take if Italy goes fascist. The moose still bribes referees, except this time it's more obvious. He returns in 1938 with the famous Italian team in all black Fascist uniforms, loaded with uruguayan and Argentine imports (including several from the 1930 final).
Austria isnt Anschlussed IOTL, so rather than execution by the Nazis, Matej Sindelar becomes famous for his goals defeating the Fash in 1938.
RIP Matej Sindelar.
If Italy doesnt go fascist, they lose in 1934 but make up for it in 1938.
1942 Argentina ARGENTINA d Uruguay
1946 Danubia ? ? (Would have to research this one more)
1950 Spain SPAIN d United Kingdom (first appearance?)
1954 Brasil BRASIL d Uruguay
1958 UK UK d Germany (only WC where all 4 home nations qualified OTL. Wales and NI were quarterfinalists)
1962 Chile BRASIL d Danubia
1966 Germany GERMANY d UK
1970 Mexico BRASIL d UK
Probably remembered as one of the most anticipated matches of all time. I'm only giving it to Brasil because of the heat.
Would definitely want to reread your TL before making any further guesses, and none of these are really guarantees but mostly feels. I could given arguments to defend these, but would also be willing to be wrong on just about any.
