This would be so easy for Gibson. The question is which direction. They could build a NR Studio bass using the same hardware as the Studio basses but with NR body and head shape, and sell it in the same price range the Studio basses sold for, or they could build (as the thread title implies) a Custom or Vintage Original Spec model with original spec hardware and sell it at a considerably higher price.
Gibson knows how many Studio basses they sold, and they know how many vintage re-issue NR Firebirds were sold. They will no doubt consider the more profitable path.
