Adding 4" would give an extra 1/2" per seat. enough for a cramped 16" seat arrangement. But that width allows most airlines to use a 7ab at least in premium economy, OK but narrow business class at 6ab and a good domestic first at 5 ab.
It already would have the stretch built in, doing the 8ab would add more than 30 seats to the plane with no change except for the seats. It would do double duty depending how it is configured, either doing the current NB routes with 40-50 more seats or doing routes 1,000 nm further than the current NB's with slightly more pax than the A321.
The 767 can take an LD3 (just not side by side) and so can an A330. Those planes were built with high cabin floors to do that. What I am reading is that the fuselage will be smaller, not bigger than a 767. The article I quoted earlier is talking about 40% lower trip costs by reducing structure.
Reports, like the one quoting Niemann above, is the NMA is a flat oval vs the more common vertical oval. I would guess it may still be a double bubble except now the floor beams are in compression, the lower lobe is minimized, possibly only fitting a LD3-45.
Boeing could be doing a narrower than 767 fuse, just able to fit 7ab with 17" seats. No one that hasn't signed a NDA is talking specifications of it.
