Adding lowering of the lightsabers' energy output for the next game

I totally love the Star Wars universe, but something has recently started bugging me about lightsabers. They can easily dismember and kill things... It would be absolutely awesome if you could add the option for jedi to lower their lightsabers' energy output so that they can just injure their opponents instead of completely killing them. This would obviously prolong battles, but it's going to be totally worth it, in my opinion. You can also add something like a training lightsaber, electroblade training sword, or even something completely new and cool like a stun lightsaber.

Killing an opponent or an animal in the Star Wars universe could also somehow mentally * jedi and make them feel echos through the Force after the death. I think it sounds cool!
