Yes Ed dialing the ailerons like flaperons up and down will act like an incidence change.

But what is the problem with flying the model with a little elevator trim in it? Yes it could become speed sensative but you said it pulls to the canopy on downlines a wing change to the negative to reduce down trim will make this problem worse. I think you are pretty good. Mix a little down elevator at idle or come up with a way to adjust the stab. If its not glued in place there may be a way to shim it. I know the Carden's use those little plastic angles. I shimmed mine.
