I have spent my adult life working with metal and built up hundreds of vintage bicycles. One thing that I do know for sure is that aluminum does NOT like to be bent. Fractures are all but guaranteed. With that in mind, there is no way that I would attempt to bend the bars back, even if they were something special. Too dangerous, in my opinion.
