Sure, body-on-frame cars (before the early 1960s) were easy to weld back into shape. With unibody cars, that doesn't work anymore. Body shops have frame racks to pull steel cars back into shape. That works if the car isn't too bent and your standards aren't too high. Aluminum unibodies don't respond well to bending so yes... If the frame is tweaked enough to screw up the wheel track, that's probably the end of the car. Maybe find a flood car with a good frame and swap everything over. This is true whether the car's body is a single casting or built up by welding 70 pieces together.
