I know that in the CK, you can toggle "Opposite Gender Anims" for an NPC. Meaning, you can make the female have male animations for walking, standing, etc. and vice versa. It should be in the first panel once you open up the Object Window. With player characters though, I'm really not sure. I've done a little looking around and I haven't found anything for player characters specifically. There might be a way you could isolate the code generated for an NPC when you switch gender anims and then try using it on yourself, but you might have to do some digging for that.
I'm not quite "in the know" enough for such a thing yet, lol. If I come across anything, I'll let you know.
By the way, apparently if you console change your PC's gender, it won't change the face or voice, just the body. It may goes as far as to change the animations, but you'd have to try to know for sure. I never have used that on my PCs, only my NPCs. It may be worth a shot. xD
