The wireless receiver for the controllers is inside the headset itself, so it’s not just the software that’s the problem, you would need to build your own receiver hardware and software in order for this to work. However you can use the USB connection on the controllers to send the data back to the computer, but you would probably need a custom software solution to read that data. A good place to start might be how developers have been able to get 3 controllers working to track their video camera for an AR overlay (like fantastic contraption did). At that point you have to weigh the labour costs of developing that solution versus the cost of just buying another headset.
