I've been in the hobby for over 50 years, and although I have not done it myself, back in the old days the magazine articles would talk about removing warps with steam blowing out of a tea kettle. Those had to be doped structures. I have also heard that dope is a thermoplastic hence can be worked somewhat with heat. I was a kid then and just tried to fly crooked models.
