Looking good at this point.
Any engineer types know ?
Short Term:
Utterly impractical on many levels. Most significantly, if the NG could compete with NEO, they wouldn't have built the max in the first place.
Long Term:
Lots of (government sponsored) new technology on the horizon to dramatically reduce fuel burn/carbon/emissions. It will take a LOT of R&D money to implement (likely drastic changes to aircraft configuration), so both Boeing and Airbus decided not to drop tens of billions in a clean-sheet narrowbody which might be obsolete in ten years. Normally they would have, and just saved the new tech for the NEXT generation a few decades down the line but regulatory and/or political pressure is very likely to force the implementation of said technology as soon as it's ready (2030, maybe sooner?).
