Papal Elections

[bilbobaggins764]

In medieval 2 total war you could elect the pope if you had a bishop. So the Popes were elected by the nations bishops, if you had multiple bishops, you had multiple votes. It encouraged you to "level" up your priest to have more votes because if one of your bishops was elected pope, it gave you great standing with the church and other benefits such as calling a crusade where you wanted to. 

Could something of this sort be implemented into KOH2? Perhaps it could replace the non historical "ruler of the world" or whatever that is.
