In-game Character Editor Tips?

I plan on implementing a Character editing system, just a few different face styles, hair, body types, etc. I’m thinking of allowing 3 body types, 3 heights, all interchangeable in game. What would be the most efficient way of doing this? I can’t seem to find a way to jump from short to tall without sliders. Would the best way be to create 9 body types so as to every option essentially loads in a new character? Or is there a way to allow specific morphing options such as a button system instead of a slider system?
