Since the Raider settlements came out, i've thought often how some of it could translate to a Brotherhood system. -Radiant Quest to appropriate a settlement to fortify -Brotherhood radio (possibly a mod in itself) to coordinate soldiers to the outpost, and spread propaganda -Brotherhood would also dislike farming, and would require you to get vassal farms (Linked with Procter Teagan's quest) -Unique Brotherhood happiness items like a Target dummy item, PA Frame constructor (requires items) I think there is a lot of potential here to increase brotherhood immersion, whether you are a White Knight, or Black Knight type character.
