Had a speeder bike not go into the back of my AT-AT properly one time, and bent the front all the way back to the main body. Taped some Popsicle sticks around it for a while, and that bent it back into shape. Might work for you too, or a mix could work, something to hold it strait while you heat, and cool it. Heat, and freeze has worked very well for me to bend some things, just cool it quickly before it can bend back.
