The one place you could potentially win is VR: each console could run the same codebase, independently, to generate the left and right eye views - whatever one console can do for one display, two can do for two; the amount of information required to keep the two game simulations in sync would be relatively small (world/view transforms and frame timing from master to slave console to let the two simulations stay in lockstep).

People would balk at having to buy two consoles for VR though.
