Just a thought it would add more choices to the game giving the game more diversity.
Also on another note the Twi'leks and there tentacles you should give us more choice of how to set the tentacles like you had in KOTOR, Here http://i40.tinypic.com/2ekrloz.jpg and here http://images1.wikia.nocookie.net/__cb20070606145232/jedipedia/de/images/2/27/Twin_Suns.jpg This will also let you be able to use a hood on a Twi'lek race as shown http://1.bp.blogspot.com/-lFqTr4vH9Ww/TlgaiS7kUXI/AAAAAAAAAsA/1BJJ-K9Tu7w/s1600/vsquad_0132.jpg
Could also add more hair styles, tattoos, colors for hair, ways to change details of the face like nose eyes ears etc.. Make the game more customizable.
