Ah, wonderful news that you are making a version for the VI expansion. You have done amazing work here!

You've inspired me to beginning planning my own small area mod. The era of religious wars in Northern Europe, particularly the 30 Years War up to the Peace of Westphalia in 1648. I'm curious to see if I can manage to remake Catholic, Orthodox and Muslim factions into the needed Catholic, Calvinist and Lutheran factions with the Pope only playing a very small role (unfortunately, there doesn't seem to be any way to eliminate the hardcoded Papal faction altogether).
