If the planform is kept the same, no.
According to the proposals for updating the 747 that were rumored about three years ago was that the same structural parts of the wing would be used but the wings would be recontoured to make a thicker supercritical airfoil. I was wondering if that was what was meant by "relofting"? Previous proposals would have put a totally different less highly swept supercritical wing on the 747 which would have been much more expensive to design manufacture and certify.
