TBH I have some murderboners. I would like the option to tell the Kervus to just buzz off, greying out their camp as if you ambushed Argoth and got Arona tossed out, possibly with variations involving killing Argoth and possibly more of them in the process. They're a band of raiders, rapists and slavers, no better than the demons. If you tried it you would have to fight another horde equal to likely twice the amount of orcs in the Longhall, plus Arona, Hretha and Infrith joining them with extra actions per round to make it even less likely with a variation of the camp-broken bad end if you fail, but if you should win over those odds you can command the Kervus to leave the Marches for good, and leave their slaves (except any who might actually want to come with them), on pain of death. Side effects of that beyond losing access to the Kervus location would be Arona's gone from the game as well, as are the other orcs like Vaush and Grettel, and even Garth's adorable pink orc-bork (actions have consequences). Or if you went all "purge" on their asses, Grettel, Vaush and a random collection of Thanes, Amazons and Shamans show up as permanently hostile random encounters instead, possibly including vengeful orcs start showing up helping out Cultists.
For the Kitsune gang, if you are already friendly with the actual named Kitsune after finishing the quest, they should just tell the roving band to leave you alone, and their encounters would change from them just asking you, with a no having them leave in peace (like if you are a Kitsune yourself) with another option for a "Spar" resulting in the same fight, just as with the Hornets after doing their quest but before purifying the hive. For the Hobgoblins, it makes sense to keep them as raiders until they can be more fleshed out with maybe a village location of their own where you could challenge a chief or the like, after which their encounters change or vanish. The Mino Miners had better fucking vanish or get a lot more polite once the Siege is over, or I'd like the option to turn them into burgers. Not remotely joking about those fuckers, ground beef is too good for them if they'll continue trying to rape the savior of their city (though offering some friendly fucking with no consequence for turning it down is another matter).
