Have to say this but it will never happen.The best way out of this dilemma would be the return of the third pilot.
The third pilot was a "roadblock" on the route from the cockpit door to the pilots and the controls.
The inclusion of a third pilot means that there would never be less than two pilots on the flight deck.
Pilots work at 25% of their maximum capacity most of the time, 95% of capacity some of the time and on occasions, when things go wrong, at 125% of their capacity. The third pilot dropped that 125% back to 95% and made the whole operation safer.
The third pilot had a 3D view of everything the pilots were doing and what they were seeing on the instruments, a much better view than the pilots had of each other. The third pilot was often the first person to detect an incipient problem.
Somehow, having a third pilot on the flight deck moderated any opinions and actions of the two pilots, a stabilizing influence.
Incidentally the third pilot increased the number of new jokes on the flight deck by 33%
