Not quite. I don't think you all realize how stupendously expensive certifying a new type is. Boeing and the airlines wouldn't be prepared to absorb the extra costs just to have a slightly more efficient 737 at the other end of it. I don't have numbers but I do realize it's very, very expensive. That's exactly why Boeing has tried to avoid a new type certification for decades, that's why they added MCAS to make MAX behave like the old 737, and I do think it's about the damn time they bite the bullet on that one. All this hassle will end up costing Boeing a lot more than a new type-certificate which would allow them much more runway in the future.
