TLDR: a mod or a way to make all religions Uncertain Nature, Primitive and disorganized leadership so every single needs to reform

So I was messing about with the shattered World settings and I decided that I wanted to see a world basically start from scratch. All tribal holdings (or nomadic I guess) all independent counts and so forth.

Then I thought I want to make all religions basically unreformed pagans (they can keep all there names) and then the first person of that religion to meet those requirements to reform gets to decide everything about that religion.

So the first person who Christian (basically in name only) meets the requirements and

bam Catholic Cosmopolitan Relgious tax Monasticism with Temporal leader or

Bam orthodox is a peaceful Stable Syncretic with their own version of a Pope

Bam Buddhist is religion that is war like

You get the point.

And these are all happening in one game and now the peace Orthodox are all in danger from the Buddhist who are knocking on there door or other various scenarios

I think it would be relatively easy to do since you can clear religion features when choosing random features on the menu.

The natures and doctrines and leadership all have options that would reflect an unreformed religion (but unfortunately you can apply those settings)
