Hacking Question Nintendo Switch Controller Spoofing

[Flusteredcustard]

Recently, 8bitdo controllers got a firmware update that allows them to sync wirelessly to a Switch with Bluetooth. Does anyone know how this was achieved, and is it possible to use that information to spoof a bluetooth-enabled PC as a switch controller, allowing for input redirection and possibly even "twitch plays" sort of things? I've looked around on the internet, but I've been unable to find anyone who has done something like this to connect to some other kind of console, so I figured I'd ask here.

It would be easy to read the controller bluetooth output and resend them using an arduino pluged to a USB controller
