I'd love a set of 104-ish DOLCH color that would be profiled correctly for the mx-11900. I took the set off my actual DOLCH board, and they're far too loose for the stems of the later brown cherry switches. My escape key shoots off like a Pog whenever I hit it off-center.
I already bought a set from the first round, but I'd seriously consider buying another if it included the keys to fit an ISO mx-11800.
IIRC, that would require different modkeys (Rshift, R/Lctrl, R/Lalt) plus spacebar, not counting the ISO differences (extra key, enter, Lshift).
Also, as it has been mentioned, a blank set would be pretty cool, preferably colored like the white/grey HHKB set.
A crazy idea would be to double-shoot just some of the keys, a blank keyboard w/ just the modkeys labeled, or enter, or esc or whatever.
Just thinking aloud...
