From your ‘immortal’ view, have you considered the difficulty in identifying a trim malfunction, particularly with a mindset of unreliable airspeed since takeoff. Add to which an immensely annoying - distracting stick shake. See many other posts, and reports from some who have evaluated this in the simulator.

Also, with the strength of wax wings, what magnitude of force can be pulled, both hands, both pilots; and for how long. MCAS training should have involved some visits to the gym.
I don’t have the stick force gradients immediately to ‘hand’, but with trim offset they can be large, and further increase with airspeed increase due to the marginally - uncontrollable nose down trim situation.
Who is going to release the stick - allowing more nose down input, to inhibit the trim, which might not be at the forefront of thought.
A third person on the flight deck; another mod option for Boeing.
