nRF52840 usb dongle as receiver?

Hi
Just dived into rabbit hole of wireless split boards and now of course I want one. I’ve been using wired ergodash clone for some time and I like it, but your design looks particularly appealing because of Ъ and creative use of 100x100mm :)
I have a question though. Now that nRF52 branch of QMK exists, is there anything that would not let me use this thing as receiver? Any thoughts?
You can try. I just used nRF51 soldered to the 3.3v pro micro. reversebias/mitosis#10
Also read wiki https://github.com/joric/jorian/wiki/Issues you may not like it so much there's no LED power switching and nRF51 in general is pretty much obsolete.
Thanks. Didn’t notice that issues page before. Nrf51 is still cheaper and I don’t plan to install LEDs anyway, so as long as it works I figured I’d give it a go.
I’m interested in your opinion though, what would you use if you’re to build something similar today?
I have a few modules used here https://github.com/joric/nrfmicro/ I'd probably use them but I don't know I'd prefer hotswap pro-micro based keyboards to dead-soldered ones.
There's a dead-soldered closed-source keyboard like this already (runs QMK nrf52 branch), SISO59 by Sekigon https://github.com/sekigon-gonnoc/SISO59-doc/blob/master/README.md
I was also trying to layout USB-C in the usb-version branch (unfinished), I think it's possible. Sadly nRF51 doesn't have hardware USB and I haven't tried running V-USB on it (there's no memory space for that).
