No, and that's not what's proposed. Exchanging the center wingbox and wing and everything in/on, is a different approach. The A300, A310, A330, A343, A346 demonstrated there's a lot you can do with length, wings and engines. Same for the 737, DC9/MD80 e.g. this may be a misunderstanding on my side....
