You're making it unnecessarily complex. The current version of x-plane does VR really well, viewport is in the pilot's seat and all you need for full immersion is a set of rudder pedals and the VR controllers themselves.
Using VR controllers, you can manipulate any modeled knob, switch, throttle, yoke, lever and trim wheel in the cockpit. With rudder pedals, it is as close as it gets to reality. I even felt nauseous after trying out aerobatics in it.
