I've been using the HHKB bluetooth keyboard as my main driver for over a year now. My feedback:
* I don't miss the arrow keys at all actually; if you haven't tried it, you could experiment with getting rid of them and seeing how you feel. That makes all "cursor move" operations consistently chorded (with the fn key, naturally).
* The HHKB allows you to connect to five devices simultaneously: 4 bluetooth devices and the USB-C connection. It allows you to switch between them with a single key chord (Fn-Control-<N>). I've found this really nice now that I'm forced to use a company laptop for my main work, as I can keep my personal laptop up and switch between them very quickly. A switch would be OK but would probably feel fiddly and annoying by comparison (and there's a risk of it wearing out if someone switches too often).
Other than that, looks like a cool addition to the solution space -- good luck and I hope it goes well!
