I forsee many an empire-wank from you in the future. I see you already are hard at work at a "Germany Wins WWI" scenario...

I am not sure how many more TL I will write, much less Empire wank ones. Overall, WW1 ATL just reshuffle who owns what, unless you have Ethiopia fall or have some odd rebellion. In mine, I did wank Kamerun for various odd reasons, but I also gave South Africa independence, so there are fewer colonies than OTL.
As to empire wanks, they are actually very easy but there is only one good POD - No WW1/Short WW1. It was WW (to me WW1 and WW2 are the same war) that ended colonialism. In 1900 or Victoria last Jubilee if you look at the information available to them, you would assume the empire system which was 400 years old would last many more centuries. And they were right, if you can avert a general war. While the schemes now seem crazy to settle non-Africans in the Kenya/Uganda Highlands or that South Africa could be white run country indefinitely or Zionism, it made sense if you keep in mind their reality. Europe was not just growing in population each year, it was growning even after exporting a couple million whites each year. Each of these countries wanted to create friendly colonies that spoke their language such as the UK had with Canada. France wanted Algeria. Italy wanted Libya. German was doing SWA and was negotiating for an expansion into Angola. Russia had an empire, it just happened to be in central asia and the Far East. Japan had the same in Korea. The USA had a low population density, so it is a bit of an exception. So is A-H for internal reasons. The Hungarian portion was trying to export non Hungarians and those that resisted Magyarization; Austria had too many internal issues to be focused.
And when I looked at these plans as backgrounds for my TL, I concluded they would have worked. France has the hardest issue with Algeria mainly due to low birth rates going back to the Napoleonic wars. Italy is easy to project into majority Italian population in Libya. Germany is the same in SWA and Angola. Japan would have made Korea and Taiwan "Japanese". It is just simple math. Take 2 million extra whites leaving Europe from 1915 to 1965 for 100 million. Gross up for population growth, and we have 200-300 million extra whites somewhere outside of Europe. A lot of these colonies had under 10 million natives, sometimes a low as 1 million. One can't predict exactly which areas are white, but there are more white settler colonies and more South African type areas.
And this is only half of the reason. These whites will suppress the natives birth rate. There will be obvious reason like the massacres and ethnic cleansing that will happen. And there will be rebellions and harsh suppression of rebellions. But it will also be through suppression of birth rates due to resource competition. Many densely populated areas in Africa now (tea area of Cameroon, Uganda Highlands, Rwanda) were lightly populated often with a herding lifestyle. The whites will simply take the better land and thereby reduce the food available to support the native population. The additional Europeans in Europe will also eat a larger % of the world food supply. Low non-European population by 200 to 600 million.
For better or worse depending on ones perspective, the world without WW1 will be much whiter and will likely still have major colonial empires. North Africa excluding Egypt will be majority Christian. There will be several more area like South Africa IOTL that will be greater than 1/6 European descent. South Africa could be majority white. The Suez will be controlled by Europeans. The strategic ports of the British Empire are still British (Hong Kong, Singapore, and some others).
