Just to make a Suggestion as I had the same issue with a dynamo cut corner control panel.. I had one that had a trackball on it, and various other sloppy holes, so what I did was just put a piece of plexiglass on top of it, drilled the plexi according to the button layout I wanted. I mean if the thing is like swiss cheese and you can't drill the holes where you want them it's another story, but to be honest those control panels are rock solid and you can drill holes kissing / overlapping each other and shouldn't have any issues.
