For me i would have a double-bladed violet lightsaber. I would have a goatee and long hair ( silver-gray hair ) an irish accent, and a black robe. and if could go out on a lim hear i would like to have the force power to make heat and cold with the force. In theory you could do this by vibrating the molocules in the air with the force to make heat and stop all the molecules to make cold. I would call it force fire and force ice. This would probably take a lot of concentration. :D
