Yes, you COULD BIY, but then think about how many buttons people would use per control panel, and alot of people have hot-swappable panels. To make a custom button holder for all of your buttons, well it would take alot of time, and im sure it wouldnt be too much fun, so I odnt think that's a great idea. Im sure you could do simple ones though, it couldnt be too hard. I was going to just drill some holes for LEDs into the button beneath the plunger, above the microswitch. A site tells how to illuminate Happs pushbuttons, so that would be my technique.
