I don't think there are models for meshes 2 (athletic), 3 (muscular), or 4 (curvy?) for either male or female. And I mean for the faces. They subtly change.
And in addition to cut scene mishaps, I don't think applying a voice modular for just a species is feasible. It's possible but probably not worth the effort. In the end, it'd be a sloppy job. I'll pass on that.
