I know Ady said no more Jedi ideas in this thread, but I have had an idea in my mind all day. What if you changed Luke's lightsaber to blue. I know it may sound weird, but think about how cool it will look. Just let me know what you think. It was originally supposed to be blue anyways.

But it wouldn't show up against the sky at the Sarlacc pit, which is why they changed it to green. Besides, if Luke's saber was blue in RotJ, then there would be no precedent for the PT to have green lightsabers, because they would have either been blue or red.

However, Ady could just change all of the green (and purple!) sabers to blue and simplify everything...
