So the outboard engine's "angle of incidence", (so to speak!) reduces as the wing bends, to become approximately the same as the inboard engine's? Would there still be a minor difference between the two depending upon take-off weights?
Yes that's right. There would indeed be a minor difference depending on TOW or, for that matter, as fuel is burned off in cruise, but those are small differences.
Now I come to think of it, the downward bending on the ground due to fuel in the outboard tanks would presumably have the opposite effect ....
