Passthrough PC

Is it possible to feed the Quest passthrough cams to my PC while at the same time playing any non passthrough game in VR?

I stream using a custom FPV MR setup on my Valve Index where I pull live footage of my arms in a green room and overlay them with the VR video game hands to make it look like my real hands and arms are in the game. I want to bring this streaming experience to the Quest Pro.
