William the Crusader - Normans invade Andalusia

Normans

If they do indeed invade and manage to conquer territory, who gets it? Would'nt the Castilians/Asturians demand some of it? Or would the Normans govern through the Castilians?
 
I was actually thinking of a scenario where in Empress Matilda marries Alfonso the Battler, that would be a start of a Norman-Jimenez clan that fights for the rights for the crown of England and the Duchy of Normandy.
