As far as seeing the sabers illuminating, I think if that should be done for just the darkest scenes. Like in the Carbonite Freezing chamber room, being the darkest. No need to worry about laser bolts from the guns because those are mostly in well lit enviroments and they quickly go by, unlike the lightsabers which have a steady glow. It doesn't have to be perfect, but some illumination in those darkest scenes would be very effective. Maybe experiment with it, see what happens. Just a thought.
