The other option is of course to add spacers to the hub. Having a straight chainline is important, but that can easily be adjusted by spacing the hub or using a different BB length.
Even if you do decide to respace the frame, cold-setting the steel is not too tough. I wouldn't try it on an aluminum frame, though.
