Yes, it is possible. How bad is the twist? While un-strung, dip twist in hot water and hold a minute. Twist the limb the opposite direction of the twist. Repeat. String the bow over night. Draw bow several times and see if the twist straightend. If not, you can go to the next step with dry heat. A hair dryer on the twist. Do not over heat. Glue will start to de-bond around 140 degrees. Keep twisting limb opposite direction. If this doesn't work, then the limb is finished.
