Pitch control with engines is absolutely possible and was spectacularly demonstrated with the Sioux City accident on a DC-10.
We were later trained to accomplish that on the DC-10 and MD11 (yes Sirs!).
It is possible to train pilots, at least those who are still trainable.

I am a heavy sceptic of all these artificial pullers/pushers/inhibitors/limiters when aircraft re-design pushes nicely and well balanced/designed aircraft out of a certain envelope.
Largely disagree (only on assumption) if a 737 MAX lost a similar surface area of tail surfaces - it seems far more dependant due length on a tail stab.

But if you are correct the pilots of the crashed aircraft pulling back power would have a LARGE pitch down effect, not good when low.

The Japanese pilots had some success for some time, using power for pitch also in the 747.
