If England stayed Catholic (many PODs possible, just take your pick)
Could Maria Beatrice of Savoy end up as Queen of England and Duchess of Savoy (OTL Savoy didn't allow duchesses, but let's imagine that bug gets out of the picture)?
And would it be possible for a England-Savoy-Austria Personal Union in the next generation with England still believing in the Divine right of Kings? Or I suppose maybe England-Ireland-Savoy-Austria...
