I'd suggest the cut as well. But with a variation. One degree isn't much of a twist. So if you cut in from the leading and trailing edges but stop at the spar. Then you can block the wing panels to achieve side to side equal angles. To join things back together use a filler "rib" of balsa or plywood which matches the kerf of the saw blade. Then cap the joint with a strip of light 1 inch wide fiberglass tape with epoxy to finish the job. That way the spar joiner holds in the dihedral but you free up the wing enough to twist the panels back into alignment.

And yes, it's worth doing. It'll alter the amount of trim needed for each airspeed as Rodney says. Been there and hated it.
