Making three religions of same religious group

[Seething Clay]

For a mod I'm experimenting with, I rather need three religions capable of offering marriage, pledging allegiance etc to each other. What I think there is in DV as it stands is two (the Christians) that can do this to each other and three (Muslim, Pagan, Jewish) that can only do these things with their own religion.

Would it be possible to make one of the non-Christian religions act as a third Christian religion?

No, that's not moddable.
Maybe you can use a trait, like the muslim shite/sunni split?

I'll find a workaround.
