Considering the amount of load that is put on a tower I would never consider using it while it is bent. Likewise, I wouldn't consider bending it back and using it. The idea of a tower failure is too catastrophic in nature even think about doing so.
I would suggest just replacing that upper bar at the first point it bolts on.
