It seems like there should be a part aftermarket here to cover the gaps after the original is discontinued or vendor goes out of business.
Maybe with the increasing popularity of 3D printing, people will start constructing their own keys and knobs for synths!
I know Rob Lee didn't like the blue color of the Ultranova, so he sent his two boards off somewhere to get one refinished in white and the other in black. They looked like a factory job, all original printing reproduced perfectly. I found a pic of the black one, couldn't find the white:

UPDATE:
Was able to scurry up the pic of the white one after I posted that :
