Biggest problem with putting the A-10 back into production; Most if not all the jigs have been scrapped, and the workers who built them have been doing something else for the last 25 (?) years.
Still probably worth doing the estimate for building another 100+ even if the new E model would be able to only have a few parts in common with older models. (Can the marines get one with folding wings and a tailhook painted marine blue?)
I thought they destroyed the tooling?
Well, step one would be to transfer close air support, together with its budget, from the air force to the army.
Re-draw the rules to give all single and twin engine aircraft not capable of sustained supersonic flight to the army. Air force would retain all current equipment with three or more engines, or capable of sustained supersonic flight.
If that works out OK, eventually transition all transport to the army. That way the fighter jocks could keep their toys, and the heavy bombers.
