Pete,
It is the wing area and planform change which creates higher loads. Bigger wing
= more lift. The bending moment at the root is calculated using the lift vector
x the offset from the root (or centreline).
The bending moment can be reduced by an amount (wing mass x offset of CG from
the
root (or centreline) datum).
Hence the heavier wing (which will have a local semi-span CG further out than
std
wing) helps reduce the bending moment, as the moment it creates acts in the
opposite direction.
The NET loads at the root for the MG will be higher.
The extra weight on the landing gear may be mitigated by the lower wing loading.
Its all in the numbers.......
