I have the previous edition of this (both bluetooth and wire) and they're great. Yes, I bought the wired one shortly after I realised the above design decision.
Bounty paid for one of these, though. https://deskthority.net/viewtopic.php?t=12329

which is an awesome idea, and also something I wish I could just buy.
So maybe a cheap pcb could be designed to connect the whole keyboard; build your own case. I'm picturing something CNC milled out of some classy hardwood.
I know I would pay for the board if it already existed, and I am convinced there is an opportunity here. I guess maybe I should bite the bullet and finally get around to learning some simple pcb design tools, but I wish someone would just scoop the idea :)
