Philip will be absolutely less spoiled than OTL and his ego would be kept down both by Anne of York and by the fact who his younger half-brother has an higher title than his own and he will die younger than OTL. Also ATL Philip will have a totally different mindset about France as ATL France will never be the OTL power, being too encircled and without any escape as the OTL Italian wars will never happen here as the alliance between Milan and Naples will remain intact.Did they? Edmund Mortimer reported a plot aimed to crown exactly him to Henry V, it doesn't seem like he wanted the crown for himself. And he died childlessly, and neither his father Roger or uncle Edmund claimed the crown for himself. And Richard had Edward of Westminster recognized prince of Wales, when he still believed Edward to be Henry's son. It doesn't seem like the actions of men wanting the crown for themselves. But why English lords agreed to such choices made by Tudor? The reasons behind this won't vanish, because it is Maximilian, who is married to Elizabeth of York. Interesting, do you think that with half-brother he'll be less spoiled than he was OTL? And maybe his wife not being Juana and not idolizing him, his ego would grow far less than IOTL.
And about England Max is still foreign so better crown Elizabeth and have him rule jure-uxoris
