using heretic as a normal religion?

[vercassivelaunos]

I want to have ten religions in my mod, and as that is the maximum, I'll have to use the heretic religion as one. Are there any issues, if I disable heretics for the rebel factions?
It is not supposed to be a real factions religion, but only a condition for certain units (I want to have Orcs recruitable in areas, where Orc culture is high). Besides that it is supposed to be an absolutely normal religion, but I'm not sure, if heretic is absolutely normal.

I used heretic religion to make it into theocratic society in FaerunTW and it works, I changed the papal faction to heretic (Elturgard) and played for several turns without any problems. Therefore I guess the faction can be heretic and work normal.
