Found these while researching.

These are 12mm so your case needs a bit of extra modding but they offer the same 4 colours as the snes controller.
Might be useful to someone.

Did anyone try out these bad boys on a DMG-01 Shell?
(would love to see some pictures)

Great find! I bought a set of these to use as the L & R buttons on the rear. Sadly, they're too large to work as the face buttons though. And I suspect the walls are too thin to remove enough material through sanding to make them fit. I'm sure you could increase the size of the face holes though.
