It can be done with some cool fab work with Plexiglas diffusing the lights. You can stealthily mount a strip of LEDs behind or underneath it. Just think about light diffusing panels in LCD backlights.
For the covers, you'll need to mold some plastic or fiberglass. Sand, and then paint the whole housing satin black. If someone can do CF housing, I'm sure this can be done as well.
In other words... do it!!!
