The only PW5's I've met in person felt so lightly built that I'd be a
bit worried about whether there is enough margin for increasing the
root bending moment as you would with span extensions. Of course,
there might be enough margin for some modestly-sized winglets but even
those will increase the root bending moment somewhat.
