I now have 4 more that I will never use.
Sounds to me like it's time to get two more MCUs, some standoffs, and some rubber feet, and make a pair of barebones boards, LOL. JLCPCB is pretty nice. I did an extremely simple custom design that was literally just traces and vias, and got 5 PCBs for under USD30.
Thanks! I've tweaked the layout a tiny bit since those pics, but I've been using it a lot and it's worked really well. Current project is to retrofit a little baby solenoid onto one of my fully hand-wired boards with tactile switches. Not exactly true IBM "KERCHUNK-THUNK!" but should add a pointless and fun audio feedback to a board I just don't use that much otherwise.
But seriously... if there is a switch type you've been meaning to try, or some weird QMK ideas, add a plate from Keychron and (maybe?) the hotswap sockets, and you've got a perfectly legitimate build style.
