Combat modifiers based on state religion?

[Ringan]

In the game Shogun: Total War the Buddhist sohei warrior monks fight well against other Buddhist opponents, because the opponents don't want to fight holy men. I was trying to figure out how to recreate a feature like this.

I would like to have some combat modifiers like +x% or -x% against a unit that belongs to a civilization with the same state religion as you. What would I need to change, and how deeply would I have to go to mod this? XML, python, etc?

Thanks in advance!

So basicly you want tho additional XML tags you can add to units:

UnitCivicName en iUnitCivicCombatModifier ?

Intresting Idea, I will look if I can add it to my BtS Ultimate Ranged Combat Mod
