Brian the car can be fixed from what I see, but you may be better off starting over with another rust free body if you are able to find one for a decent price. Looks like you would be replacing more than half the panels of your car to fix it.
Also you mentioned an attorney if needed. First most attys don't want anything to do with property damage stuff. Second they don't know much about it anyway.
If the time comes we can use the appraisal clause in your policy to get you a fair settlement. No charge for me to do this for a fellow mopar brother. This is what I do for a living is help customers get settlements for total losses and diminished value on insurance claims.
