1) Yoda 's race as a playable character. How fun would that be?
2) Customization. Like SWG you could make it a skill or just have a vendor that you could pay to change your appearance or that of your Armor. customize the look of your ship as well.
3) Space missions maybe tie in missions to crew skills. i.e. you have to deliver said part to hutts through mandolorian pirate space. or you find a wrecked satellite or ship and can scavenge crafting materials.
Thanks
