Repairing pitting in cuda hood inserts

It is possible to mount the part in a milling machine and re machine the contours, removing maybe as much as .02 thickness if necessary to remove all the pits.
This would take days to complete.
To map the parts and write a CNC program would be smarter but then this question will arise.. Do I restore or do I create a mold to reproduce the parts ?
I know which answer the aftermarket/smart money would choose.
