Refering to your original post, RumourMerchant69:
Correct me if I am wrong, but your suggested load alleviation would not change anything on the bending moment on the wing root!
If you deflect the ailerons upward, the loss of lift on the outer wing has to be compensated by the inner part - the resulting bending moment on the root is exactly the same! With your suggestion you can only change the bending moment over the wing spar(s).
If Boeing had planned to ease the load on the wing-fuselage connection, a reduction in takeoff weight would have helped them - instead they reportedly took 10 tons of water ballast on board.
