Sounds like Kimmer isn't the one being overly optimistic...I'd be willing to bet big money that it's hurt worse than you think.
I'd have the second the concern that the unibody got some serious flex there and needs a rather fine-toothed comb dragged over it to check that it is straight/correct on all dimensions. The inner fender well is an indication of frame/shell flex that sprung back, but that doesn't mean it came back straight...
Hope I am wrong...
