If the outsider is one of the parents wouldn't that make a half-fiend? Also I'm definitely on board with different visual cues for tieflings besides a standard head and tail. Maybe short bat like wings, horse/satyr like lower legs, claw hands, etc.

I agree if mechanically possible. Would be nice to be able to color the current tail at least even though people rp that it is a different color.
