Could you side with Islamic nations per say? Like if Bzantium was attacked by other Catholic nations, will it be able to have a few Islamic allies for a price? Will Italian city-states, be like republics or kingdoms? Are you able to control the Pope like a puppet if you control the lands in Rome and the Papacy? Are you able to exile or even execute the Pope? If one of your cardinals becomes Pope do you get a bonus for it? Also can you somehow reject the Pope's wishes and demands with a certain price? Are you able to give tribute and achieve higher standing that way with the Pope? Also, can you take the land away from the Church? I know all of these questions are quite bizare if you will, especially when looking at the history, but I think it would be nice if you could do some of this.
