Trying to model the geometry of another species out of a human baseline geometry has severe limitations. There already are beast/non-human morphs for the millenium figures, but the more they diverge from the human norm, the less effective they become. This is why I would still go for the 'conforming replacement body parts' approach that was used so effectively in the Monster Parts sets, along with matching texture sets. This also lets existing clothing and morphs to be used on the orginal parts. Bill
