I'm satisfied with the amount of races that currently exist within the game so I haven't really given the idea of adding more races any thought, also the races that are already in the game are kind of my picks as well (minus a couple of them). However, I'm always open to the idea of adding more if a suggestion is good. If you have a specific race and/or a mechanic for it, I'd be more than willing to give it some thought.
As for the male path, unfortunately no, that's not really in the works. Apart from the fact that a path like that would essentially make it a different game, the whole shrinking/small, humiliation thing isn't really my cup of tea.
