The amount of roll induced by the stab twist will be very, very minimal. It's the sort of thing that a pattern flyer would notice but most others would not ever be able to detect with any degree of certainty.

However what you ARE going to find with that twist is a strong tendency to climb that will require a pretty good amount of down trim to equalize.

Go easy on the heat if you try that option. I strongly suspect that by the time you get it hot enough to let the wood and resin ease up to twist it back that the paint will be bubbling and peeling off. You may be "stuck" with Dick's option along with a bit of paint touch up.
