Thinking right field and going back to basics would not an aerodynamic fix be better. Then MCAS would not be needed, may even remove the need for a stick shaker. How, well Lear did this on one of their models think might have been the 35 by adding what they called Delta Fins under the end of the rear fuselage, provided an up force at high angles of attack to push the nose down and stop a super stall so no stick shaker needed, think the model had a T tail. Of course on the Max may need to place one each side of the fuselage rather than under so not to scrap them on the runway on high angle landings and takeoffs. I think it would be better than playing with the electronics which can always fail. Also the extra training need would go away.
The fins are delta shaped and mounted at 45 degrees down bit like an invert butterfly tail.
