That's actually very cool looking. I would keep the retheme as it's one of a kind and well done. Try brighter bulbs as has been mentioned. Get the brightest thing Comet has available and see if that helps. Otherwise I might try cutting the decal around the inserts, depending on where they all are and what that would do to the art. Like Cheddar mentioned...maybe add bulbs somewhere else to take their place. Make some custom plastics with the bonus indicators integrated somehow?
Rather than convert it back, I would resell this one and just buy an Alien Star if that is what you really want. Someone out there will appreciate this as it is I am sure.
