Sorry for the silence; Real LifeTM has taken up too much of my time in the past week. However...
I have taken apart my Poker II, measured carefully, and have re-designed the SD-60 to fit a stock case. For those of you who didn't know, that case has horizontal braces running between every row, so the Teensy just squeezes in. The Teensy with USB port plus the IC socket I used on my JD45 is 0.050" taller than the case stand-offs. That means either a very careful attachment of the Teensy without any socket or risers OR a few washers under the PCB.
But it will indeed work.
Also, as a bonus, I am now able to fit an MX-only ISO Enter position onto the PCB.
I also have the 0.093" PCB material, but have not had the opportunity to drill it out to test for stand-off compatibility.
That is the news for the day!
