Is it spooky that if Henry did get elected HRE he would be the 8th Henry of Germany as well as EnglandIt was made for him
And with a P.O.D of 1502, Ferdinand I, Holy Roman Emperor was only born in 1503 so you could kill him off too.
Depending on how the chips fall, there's a possibility that Maximillian and Margaret might want to divide some of the combined Haspburg and Trastamara domains between the 4 sisters. I think Eleanor will still get Castille and likely Aragon unless they reject her for John III of Portugal. They might try to divide Burgundy and HRE between the second and third daughters i.e. Isabella and Mary respectively. Perhaps the second girl will be given the Duchy of Burgundy before she marries. I wonder if sometime down the road, Eleanor will get a challenge from her youngest sister and her husband John III of Portugal for Aragon as John would be Ferdinand's senior male heir and at least grew up in the Iberian peninsula.
