Diplomacy feature idea: Surrender independence

[LetMeIn11]

... and become one with the chosen faction. The idea is to color sectors in the faction's color and make your standings sync with your faction standings.

To punish player for going rogue the faction could directly seize player assets and do some other equally nasty things(seizing credits and sending player to manually mine ore to compensate losses?)

Trying to get freedom once again, depending on a faction, could be a more terrific experience than the end-game crisis

Some of these, for example the seizure of assets, you can already have with the mods Crime has Consequences and Professions and Reputations.
