How could we have the Byzantine Empire be dominated by Vlachs/Eastern Neolatins and not Greeks?
Not sure, but you can have the Vlachs form a similar entity to that of the Holy Roman Empire. Dunno how someone like Vlad Tepes can rule the Byzantines though.
Impossible. Greek almost always made up atleast a plurality in the population of the empire.
