I know few people who have xeno chars, and all of them are good RP players, but what xenos makes special is restrictions you are talking about, there is no other faction who has that kind unique relationship with other Sirius.
And mostly people who fly xeno char are in one faction, maybe more, couse i see lot of multiclaning here, so i fly xeno for fun and thrill being chased in VHF by whole fleet and then survive or eventually kill someone
I think if someone could make good RP story for faciton of xenos is Doom and Yngen
