I think that twist should be fixed. As Brock said, I think it can be done with low heat, but I also recommend contacting Chris cox (I assume the bowyer?).
Also could consider the bow hospital. They are a sponsor I think. And there work is supposed to be top notch.
Lastly I have corrected some mild twist in one glass bow using nothing but running hot water, and twisting the limb back by hand carefully .... It was not a valuable bow though.
