Walt,

Sounds like a good idea, but many important primary loads are
tricky to duplicate on the ground.  Plus a small miscalculation
in the loading pattern may fail an actually OK structure.  Supporting
the wing, or if you choose, the fuselage, to hold 6 or more times the
gross wt of the AC without support-related damage is
nontrivial.  Not that it can't be done, but that it does need to be
carefully thought thru by a structural engineer or even better
the aircraft designer.

Done carefully and technically correctly, this can do a lot of good,
but for example, how easy would it be to sandbag a winglet?

Good idea, not very easy to accomplish in real life.
