In any non-normal situation flying the aircraft manually usually comes at the expense of reduced capacity for troubleshooting and decision making. Deliberately increasing workload would be an unusual step to take.
The 737 Max accidents are (IMHO) mainly influenced by design choices that should never have passed certification and trying to slap a sticking plaster on top of those decisions is missing the bigger picture.
For the 737 up to NG one switch disables automatic trim while preserving pilot electrical trim, the second switch disables all electrical trim. On the 737 MAX either switch disables all electrical trim
Manual trim of a significantly out of trim aircraft may be difficult at best.
I have asked how well this change to the cutout was documented in the conversion slideware but have not seen a response.
