I don’t see the big savings in this kind of operation, but if you could reduce the cockpit to a single pilot cockpit then I see it would mean a lot in savings. But to have a single pilot cockpit in passenger flights, would mean that the A/C automation level would be able to do everything by itself from Thrust Levers is advanced on take off until it reaches taxi speed after landing, due to incapacitation of the pilot on board at the most critical point of the flight phase. And then you can ask yourself if the pilot is relevant at all.
