This is an ideas thread but I don't know if it should go into CK II when it's something that's conceivably moddable.
I've noticed that DVIP adds the Order of Santiago, which is cool so there's another knightly crusading order there, but I'm wondering what other historical groups that were province-worthy are missing. Now, the Catalan Company did not actually own territory as far as I know. But what about the Hashshashin? They could spring out around Alamut randomly and be like the Muslim equivalent to the Templars, except when you are friends/allies with any of them you get bonuses assassinating religious enemies.
