I think of flap extensions as bigger flaps......full flaps with a slip in a Stinson is the real deal!
Have no idea if this proposed mod is EXP or STC or Field Approval. But regardless of the paper side, I'd guess it would be taking a little off the aileron and put it on the outboard end of the flap?
However, adding another 6 inches of chord length to the flaps would be a better choice than shortening the ailerons... as long as the control system structure could handle the extra air loads. The trailing edge would no longer be straight, but that makes very little difference at these speeds.
