Margaret Tudor

WI: Her marriage with King James IV of Scotland never occured. The negociations somehow fall through, due to possible French interference. Possible other marriage prospects? King James eventually marries a French princess.
 
A Hapsburg would be a plausible solution in my opinion. After all, if the Scot refuse the marriage because of French interference, it's plausible Henry VII marries Margaret to an ennemy of France (a Hapsburg in this case).

An Iberian Prince (Spanish or Portuguese) could be another possibility.
