I would like to see more playable races from the more recognizable species in Star Wars. Kel Dor especially, since I've always preferred to play them in games that permit it.
The arguments against many of the popular suggestions for races, like the Voss and Wookies, don't work for Kel Dor. They demonstrably can speak Basic, they can wear humanoid clothes, and they don't cause any story conflicts, less than the Cathar even.
The only issue is romance scenes, which can be easily solved by fading to black before they kiss.
So to sum up, please add Kel Dor! I would be more than happy to pay for them.
