Old post, but a Google search brought me here as I was contemplating a similar project. I'm curious what kind of progress you've made so far.
As for me: my motivation is just for my use case. I have K(V)M where I can share my mouse and keyboard between my work and personal computer at home. I use the numpad, arrow keys, home/end/etc a lot at work, but they're not really all that necessary for my personal computer. And all those extra keys make the keyboard kinda wide when gaming. So I just wanted a way to magnetically attach the numpad to my keyboard. And while I'm at it, I could also add another module with panel of macro keys. I'm considering learning how to design my own PCB just for this use case.
I wasn't terribly worried about having all the components able to communicate when disconnected, as that would add complexity/cost (do I really want a battery and daughterboard in every module?). I never considered a screen either: it adds cost; I don't need one to tell me which layer I'm in because I'm actively holding down a key (except for caps lock); and I prefer dongles over bluetooth, so I don't need a display to tell me which computer I'm paired to. I think a Stream Deck does everything a keyboard screen would do, but way better.
