Otherwise, you are effectively designing in an Empire break up and civil-war. Not something I really see as being desirable in terms of how the Warhammer world should work. I don;t see any way of ensuring a permanent alliance or vassel state kind of setup that would be sufficiently workable to feel right.
you could hijack the catholic system and have one "papal faction" such as reikland which discourages the other states from fighting with each other. this "pope" would probably have to be more strict though. it depends whether modding it in is easier than modding it out.
