The only option I can think of would be to skip the leotard route (well, you'd still use it as an undersuit). What you'd do is build up Tron-esque armor out of some clear formed plastic (acrylic, styrene, etc.). Mask off your circuit pattern, and then lay down an opaque OR translucent blue color, preferably of the day-glo variety. Then insert a crap-ton of UV leds or UV cold cathode tubes (in protective acrylic sheaths) into/behind the armor.
It should cause all the painted areas to faintly glow, and the clear areas to brightly glow. Plus you can still create a secondary circuit pattern on top of the armor with EL wire. It still probably wont show up very well under bright mercury or fluorescent lighting, but at the very least you'd get a glowing 3-d effect, and in a dimmer area you'd just be spectacular.......so long as you're not flaunting your moose knuckle for the world to see. Please wear a cup.
