I don't know of any mods, but using changerace in order to get the correct race and then changesex to the other sex and back will result in a racechange without any weird faceglitches or statresets. In addition, if you want to customize your face I read somewhere that its safe as long as you don't do any of the big changes (race/sex) so setting them with changerace/changesex and then using showracemenu should let you completely customize your character without any weird bugs.
