If the Greek civil War turned out diffeeently, I would expect the Anglo-Americans to prop up a Kingdom Of Greece that would consist only of Crete+the Aegean Islands, the Ionian Islands, plus Cyprus, if the British are feeling like it. So that’s definitely one there.
Apart from that? Perhaps after the Russian Revolution, an Russian Provisional Government In Exile could be proclaimed in, say, Alaska as an American/British puppet state had the Americans not purchased the land, in Transamur as a Japanese client state, and so on.
France or Portugal could have revolutions forcing their governments to flee to their colonies, but I don’t know how sustainable that situation would be, and I think they would be forced to give indeendence or extensive local autonomy to the colonized, it might not even be the same nations.
That’s pretty much all I could think of right now.
