If the Gagonite have any game experience of worth, he can see right through your bluff. (I'm willing to bet he believes you though) You will need atleast 8 Papal favors (more like 9) to call a Crusade to Turkish settlements. Due to the distance between Spain and Papacy, the Jihad can be long over before you earn that amount of favor.
BTW, how exactly do you wish to split France with England? You to Take Bordeaux, Toulouse, and Marsaille, and he to take Rennes, Paris and Rheims?
PS: I do hope you sugar-coated your threat enough so he won't see you as a direct enemy. You might ask him for a favor in the future...
