I will point out that, for Seekers, dropping the tribal prefix is akin to using a familiar nickname: a lot of Seekers take affront to people they don't know doing this. If K'oga grew up in the K-tribe, he'd likely have internalized this to some degree or other. He could very well decide that dropping the glottal apostrophe would be a better alternative, and become Koga.
I do think that it's more likely he'd leave the tribe than be exiled for being a half-breed. He's a half-breed either because his mother or his father was a Keeper. If his mother was a Keeper, she'd have to have been part of the tribe to begin with (Keeper females mating with the nunh of a Seeker tribe are rare, but not unheard of - C'kayah's maternal grandmother was a Keeper who did this). If his father was a Keeper, it implies that he was an outsider who boinked one of the tribes women. If being a half-breed is that bad, then K'oga would have either been killed/given away as a baby, or his mother would have been exiled with him. All of this implies that, if he was accepted enough to grow up within the tribe, that he wouldn't later be exiled for being a half-breed. Being exiled for something else is another matter entirely...
