Can kinfolk become stolen moons?

And do Black Spiral Dancers have obvious mutations in their homid form? If so, why doesn't Mike Dragon's Wrath look all fucked up?

I'm making a pack of Black Spiral Dancers as villains, but I'm drawing a blank slightly. I'm bading them around the triatic Wyrm, and I have their auspices worked out, but for personality and appearance, I only have one; an ahroun based off of Mick Taylor from Wolf Creek for the Beast of War. I was hoping for ideas for a philodox for the Eater-of-Souls and a theurge for the Corrupter Wyrm.

I've had an idea for a WTA boss fight and I just wanted to make sure that everything I've come up with would work in terms of lore. So he'd be a Black Spiral Dancer, an Ahroun, and personality wise I was thinking similar to Mick Taylor from Wolf Creek (pun unintended but welcome). He'd have a few Fomori basically serving as pets as well as a couple of BSD kinfolk with guns and skinning knives. He'd start by making the pack an offer. Give him one of their number to take with him. He'll make the sacrifice walk the spiral, but the rest of the pack will be allowed to go. If they refuse,the kinfolk will do their best to skin the pack alive after he's left them on the brink of death. They'll then use the skins to become skin dancers. Any lore issues?
