I could be wrong, but I think the mechanics for whether or not the Christian religious head grants the invasion are hard coded and he won't grant it for someone with fewer holdings unless you have a claim on the primary title. The other invasion types have very specific conditions for when they can be used (and use lots of can_use conditions in the cb_types file), but Christian invasions are done differently.
