Religious Uprising Feature: moddable?

[Tyrian]

The force and the probability of the attack can be proportionnal to the actual dominions in the province. The order/turmoil balance can also have an effet.
For example:
chance of attack: dominion% +3% by rank of turmoil/-3% by rank of order

Attacker force equivalent to 20 gold * dominions

With that sort of mechanism, the majority of the attack can be easely beaten by some cheap defense (like 10).

The unrest and population can also play a role in this.
