The activity may be on the top of the wing, however the pressure difference is what does the actual work, and the higher pressure is below the wing.

I doubt the turn-induced imbalance accross the propeller face would introduce greater pressure on the wing, so it has to be greater suction...

If you're trying to say that the air through the propeller affects the wing, then you may be correct inboard, however there is no way you could be correct with respect to the outboard section of the wing. Aeroplanes of this era flew at up to half Mach, so there isn't time for the air from the propeller to get to the tip of the wing before the wing has moved forward.

There definitely is suction ahead of the propeller blades though: That is how the prop works...

No. Gravity is an attractive force, magnetism is both attractive and repulsive, pressure is purely repulsive. There is a pressure imbalance between the front and back of the propeller blades, and the pressure behind the blades pushes the blades forwards, that is how a propeller works.
