One of the biggest hurdles to any new mid-market aircraft is that currently there are no modern engines in the necessary 40k-50k lb. thrust range. So someone has to step up and commit to spending several billion dollars to develop a suitable engine.
It is probably just the marketing department why it is off the table. I do not see how a new NMA could improve on the 767 with respect cabin layout or the general wing. Also composites do not make much sense.
The only new engines that come close are the Trent 7000's, which are slightly overpowered. Maybe they could base it on the MD-11 instead and use 3 Leap 1A's? ;-)
