One quick and simple thing you can do is to remove the standard set screw and replace it with thumb screw. As I have done this with several of my sabers . Here is an example pic.
This pic also shows another small mod that I did which is adding a 2nd set screw and drilling small holes ( windows) around the emitter.

I've seen this sort of thing done before and I've always thought it was a good idea. Plus, I like how you chose blue thumb screws to match your blade.
