The idea of NMA (797) addressing both Boeing markets (737/NG/MAX and 757) is pretty optimistic but possible I guess
Officially Boeing talking about NMA and FSA as two separate projects. However the statement of new Boeing CEO on the article I posted before, about rethinking NMA from a clean sheets design, makes me wondering if combine NMA and FSA might be something that Boeing should do.
Boeing already got huge hit by MAX, I read an article talking about costs already USD 21 bio due to MAX and the end still not clear. Perhaps they can't afford both two separate projects of NMA and FSA and one project combination of both is the answer.
I just think, like Airbus used C Series as A220 for smaller capacity market, Boeing should also optimised E2 on that segment and thus fill at least half of the need for FSA.

One good think at least in my opinion they are now already in flight test phase off 777X..which at least positive progress compared on continues negative image news on MAX, KC-46 and their space projects. However this 170-270 pax segment is the main market on Airlines Industry..thus this combine NMA-FSA perhaps if they can design it properly will be the answer that they need for competitive edge in future.
MAX too damages in image and reputation, to be able to challenge A320/321 neo now, let alone the LR/XLR of A321. If FAA and other regulators already let MAX back into air by mid or end of this year, they should just let the MAX production line open for 5-7 years and killed it when NMA ready. Hopefully whatever design that come out can combine both NMA and upper half of FSA need, since in my opinion after this MAX episode, they simply can't afford to have both separate projects (to be able to catch up quickly) against Airbus.
Besides, I think most Airlines will think it more positive for one model able to cater 170-270 pax segment in efficient and effective costs.
