There is no MOM. It's not happening. It's dramatically more efficient to operate a very large narrowbody (Max10, 321neo) than a very small widebody.
If MOM made any sense, Airbus would be working on it while Boeing tries to right itself. The economics don't work. Even the smaller 787 and 330neo have questionable business case. Going smaller than that is a non-starter.
When the 767 was designed, aviation economics were completely different than they are today.
