WI Grand Alliance won Spanish Succession War

Let's say in 1709 the Allies did not demand that Louis XIV use his own army to eject his grandson Philip V from Spain.

Like OTL, Louis agreed that the entire Spanish empire should be surrendered to the Archduke Charles, and he also consented to return to the frontiers of the Peace of Westphalia, giving up all the territories he had acquired over sixty years of his reign.

He also agreed to furnish money to the Allies for them to be able to force Philip from Spain.

And as a result, without French support, the Allies were successful, and 1710, Charles became Charles III of Spain, and a treaty ending the war, with France giving up all territory gained since 1648, was signed.

Then in 1711, Joseph I died, and Charles III also became Charles VI of the Empire.

So what now? Charles VI has now recreated the empire of Charles V. France was now shorn of the gains since 1648, meaning no Franche Comte, Alsace, Roussilion, etc.
 
The Britishand Dutch will not care for it and will demand that he cede the Soanish throne or Austrian throne to a relative.

The problem is, Charles VI is the last of the male Habsburgs. He has no male relative, to which to cede any throne to.

And unless they got France to their side, Britain and the Netherlands won't be able to do much. And France, especially Louis XIV, would demand a high price for his cooperation.

And France is too exhausted and too bankrupt to fight another war after being defeated in TTL's succession war. It needed a period of peace before being able to fight another major war.
 
Likely the other powers will accept the new status quo forcing Charles to sign a treaty in which he declare who the union of Spain and Empire will be only personal for his reign and after him the two countries will have again separate rulers.
So if Charles had two son one will be Emperor the other King of Spain if he has a son and a daughter the son will be the next Emperor and the daughter Queen of Spain and if he has only one child he must name heir of the Empire (or Spain) one of his nieces (the two daughters of his brother Joseph)
