How bad could end Spain in 1715?

Hi guys! I was wondering if it would be feasible that Spain lost colonies in America with the war of spanish succession. what I mean is if it had been possible because of a treaty of partition, or due to the conquest by England or whoever, Spain might have lost some important territory, such as Cuba, the Philippines, or any other territory that eventually remained Spanish 1715. I´m interested in large losses of territory.
 
Maybe if the French do better and end up having to sell of some chunks to get their personal union?
 
Could it be possible for England to keep La Habana, as well as the rest of Cuba?
Anyway..did some of the spanish possessions in America entered into the negotiations for the partition of Charles II inheritance?
 
Charles VI of Austria keeps the throne of Aragon, while Philip V gets Castille. It wasn't unlikely until Joseph I of Austria died.
