I can not agree with you as both germany and italy united in the industrialisation era. even yugoslavia was formed after WWI (If I remember correct it means united slavs) so if there in reality was talk of union I consider it very likely especially if both still have the same goverment as during the union talk. after all greeks would just be another people in the union
But there's clear difference. Germans were all Germans, speaking same language and all German states had quite similar culture etc. And because of Holy Roman Empire had existed for thousand years Germans had some kind of connections. Also many of German intellectual had clear nationalism about uniting Germany.
In Italy same, all Italian states had same culture, nationality and language. Italians as well as Germans thought that they were same nation, just split up but could re-unite. Even in Yugoslavia they were almost all Serbocroats, different culture and religion, but at least almost same language and by the way the union was forced by foreign nations (UK). In 1920s and 1930s Yugoslavia was not very coherent nation, of course they had central government but still. And after WWII they had strong leadership Tito. Tito died and nation split up. And all Yugoslavs were Slavs.
But about Greek-Yugoslav, well they have completely different culture and language. They aren't all Slavs, actually Greeks and Yugoslavs didn't have any connections and... Well do you really think that nations without any connections would form a union just because they have similar governments and they think it's cool to form an union. Nowadays, actually always after WWI the thing what almost all nations have wanted is independence. In reality nobody planned about union, not (for example) Soviets or Yugoslavs about union if Greek government falls and Greece becomes socialist.
If we add any alternate history elements, it should be as plausible as possible. Imo there's two kinds of alternate history, "historical alternate history" (where you first introduce yourself to the things what happened those times, and then start to think what could happen)... And then there's 'ahistorical alternate history', where you just think "Hey it would be f****in' cool if Albania and Siam would form alliance called 'Axis of the World'" and then you start thinking how you could 'modificate' real history to make this plausible or even 'plausible'. And in my opinion this alliance between Greeks and Yugoslavs is just ahistorical alternate 'history'.
And for
Vladimir II: I readed Wikipedian article
Serbian-Greek relations which is redirected from Serbian-Greek friendship. In my opinion it hasn't any information which would make this idiotic alliance plausible.
But if you really want events for this alliance give 1 % chance for the alliance.
