Can I Change Imperium Requirements?

[Iyerbeth]

I'm wondering if I can cannibalise the imperium (fame level) system for an overhaul mod I'm trying to design but I can't seem to find anything regarding when your imperium level changes so I was hoping someone could point me in the right direction or tell me whether it's even possible.

Specifically I want to change imperium strength from being province based, so I was wondering if there is anywhere I can set the province requirements to 0 so it never triggers and then have it changed conditionally through lua script based on other variables (or db keys, though I think that's unlikely). Is that possible?
