Boeing has started working on a 737 MAX replacemen...
Modern wings could be retrofitted to the 747. Maybe not completely, but the more important features. However there are a lot of other parts of the 747 that don't make sense, and so not enough buyers (if any!) would exist if they did.

The 757 started out as a re-winged and re-engined 737. It turned out to be cheaper to design a new airplane.
