Motion controllers will probably be incompatible with this kind of setup.
VTOL VR has the best implementation of cockpit integration in my opinion. When I play that game, I want to sit on a small chair with adjustable armrests and nothing else around me. It gives me better immersion than any other sim. To be fair, VTOL is not really a sim, and it has fictional aircrafts custom made for VR. Still, I hope MSFS can copy at least some of the ideas.
