Nothing keeping you from doing it. It'd probably be best to go off the wires for the backbox GI. You can get the standard happ lighted buttons (https://na.suzohapp.com/products/pushbuttons/75-0004-1221044), and just use those. You'll have to drill your button hole a little bigger, and cut the two anchoring tabs off the button. A little woodworking, but hardly a killer project.
