Let's say France wins the Napoleonic wars. Never mind how exactly this victory is achieved and how total it is, or how does the map of Europe look exactly, except that Joseph Bonaparte remains King of Spain under French protection.
Let's say Napoleon dies childless, while Joseph is still alive. Does that mean that the Crown of France goes to the King of Spain? IE does that mean that France and Spain are now under personal union? That could have a lot of consequences, I think. Is such a union possible? Would there be anyone who would be strongly opposed to that? If so, who are they and on what grounds do they oppose such a union, and if not, then I'd like to know why everyone is so willing to cooperate with something so big.
