Not yet.
There were inkjet CPO's reproduced a while back by Archer but I'm sure they are no longer available.
One can only hope they will be done again.
oddly enough, i just talked to someone about this earlier tonight. I have a gravitar cab with fantastic art, except the white around it. Mine is perfect for scanning
This list has 90% of the arcade artwork that has ever been reproduced. Gravitar, like you said, only Archer prepped composite sideart files. The CPO might have been done in vector.
