Rebuilding the Millennium Falcon 7965 with unsorted bricks?
Only ever throw out LEGO that has sustained actually irreversible damage, bricks that have been bent beyond repair or snapped. It so rarely happens that I can find a suitable picture. In this case, I would assume the longest plates and tiles would be more likely to be damaged.

I'd go through the painful process of dismantling the model and starting again, replacing any broken pieces (if any) or at least starting again from the last significant building stage. Many large models are build independently and combined at a later stage of building. These independent 'building stages' often match a numbered set of plastic bags.
