New internal empire crisis type

[LordLeviII]

I love the precursor lore with internal factions rising up and that is what destroys them, could there be a version of this as a 3rd crisis event for players empires?
Fanatic xenophobe gets xenophile rise up backed by other empires and forms a federation against you or vice versa.
Rogue serviator gets a rebellion of bio pops that use ameoba and whales or something crazy!
Even using some events from precursors like the psionic war one.

Some sort of decadence mechanic for normal empires would be cool, but is better for a mod IMO. Most of the fun of the game is building your empire; watching it turn into a fallen empire is a very niche taste.
