Honestly, why do one when you can have both? There's seeker of the sun Mi'qote's and seeker of the moon ones aren't there? Just have one of the races have really buff man cats like the BoF characters like Rei and Cray, and have the more slender effeminate types for the other. Problem solved, and it would make more sense anyways for different clans to look different as well, setting them apart from each other so you can tell.

Though along those lines for other races, I hope they include a Roegadyn clan that has tails and looks like the galka of FFXI.
