Sorry if I am a bit repetitive in my choice of topics...
The POD would be Charles d'Anjou-Durazzo (II of Hungary and III of Naples) getting good wind of Elizabeth of Bosnia's plot to kill him and thwarts it, killing the would be assassins and imprisoning/forcing into convent both Elizabeth and Mary.
He seemed to have a good degree of support from the Hungarian barons and was in more or less complete control of the Kingdom of Naples: could he manage to keep control of both his reigns and pass them to his ambitious son Ladislaus?
A power controlling both sides of the Adria would certainly encounter the hostility of Venice, then there is the mess of the papal schism to consider, ti say nothing of the looming Ottoman menace and potential rapacious interests from Poland and the Holy Roman Empire, but a Naples-Hungary union (eventually Italy-Hungary?) seems to me to have great ATL potential.
Another possibility would likely be under Louis I, if his 1348 campaign was not thwarted by the plague (maybe delaying the Black Death for a season by sinking that Genosse ship from Caffa?)
