Front collisions will always drive the middle of the core down and in, and away from the collision direction. In my experience you need to return the interior dimensions to correct in order to get the core to fully straighten out and not cause the middle to sag.
Short term solution is to use washers to boost the nose panel to correct height, and massage everything else around to fit best and leave best reveals with the best solution to have a body shop straighten the old one if possible or replace it.
