May be and due to the fact that the new repro overlays are much thicker now, this could be a possibilty using a sanding disc to strip off to bare pot metal, provide a smoth surface and than to glue on the overlays and finally to polish them to have a closer approach to the more shiny orginal.
Sounds like a hell of work with a questionable result...
I asked within that thread about the reproduction consoles and since, have seen one at the counter of NPD in Michigan. They look pretty good, fitment still unknown but if I remember correctly, you have a convertible. The reproduction console is made to fit non A/C coupes & fastback and require trimming for A/C cars and convertibles.
Otherwise, yes, if you grind or machine down the faux brushed aluminum surfaces of the console and make the surface uniformly smooth, the overlay kits will look better than the pitting but it will never have the sheen of the original ones.
