Honestly +1, I think the addition of guild lore characters, especially relatively minor ones could be good for passive RP. Let them have a little more lax of rules on what they can do against the republic and then let some people be guild mains and have fun lol.
Yeah theres the issue with maybe some of them like Bane being used for events, but if thats the case then A. don't add ones like Bane who are frequently used (I would argue Bossk for example isn't) and the B. just use them anyways even for events still, who really cares if they're a lore job.
or honestly just add Boba/Bossk and that little squad and run them tryouts and such with a little leader.
