It may be possible.The biggest problem is that the movement wouldn't go with the body if it needs to be assigned to more than one bone. It wouldn't bend with the body. ;c (I've tried with a backfin item I've made that's in the works.)But if it were head-only, then I'm sure it'd be great! The only other problem is the texture/ color not easily being changed. It'd be more like Presets.
This would be a nice feature, but I can't see it happening. It would be very hard to get it to flow with the rest of the body, and would consume a lot of time. I may be wrong, though!
