Wouldn't it look awesome to light the Pro plastic ramps with fiber-optics, similar to Tron? It would look like LIFE-SIZE LIGHTSABERS on going up both side of the cabinet! Imagine flashing them during the saber duel modes!
Edit: Add some lightsaber handle plastics at the bottom of the ramps, and it would actually look like two lightsabers flanking the playfield.
Edit 2: Add VERY crude mockup...
