Quest Pro Controllers Connect Direct to PC

Is there any way in the SDK to connect directly to these controllers from the PC?  It would be great to be able to use them as stand-alone controllers for use with other headsets such as the Big Screen headset.  Surely an Open VR (or something) driver could be written to replicate the communication mechanism that currently going on between the Pro/Quest2 and these controllers?  Though I guess that doesn't aid Meta's revenue stream so it will probably never be exposed.
