Try boiling the part you want bent for about four or five hours. then lock it in the jaws of a vise just tight enough to hold it and try to slowly straighten it. You will also need a way to tie it to something once you get it started bending so that it don't draw back to the original shape when it dries. I have done this on skull mounts to even the antlers out when one side sets higher than the other, but I usually only move them an inch or two. Good luck.
