Yeah the further you are in your transition the less desierable your body becomes to our mirror twins. it's a shame humans arn't made out of lego!
another friend of mine has really rotten back teeth yet I keep getting more wisdom teeth than I can handle making mine all wonkey at the front. I'd gladly give him some of my spares.
Although my voice is passable I'd be more intrested in swaping larnyx's

For that a guy can have the whole shibang my old voice plus two T factories and a penis if they want it they can have those 4 spare teeth too.
Face swapping would be cool too ^_^
