Skigs - when I replaced my 2012 cushions a few years ago with the remaining OEM stock I could find online, I was doing it primarily to get rid of any discoloration or cracks the old vinyl had. However, once the replacements were installed, I realized just how compressed the old foam had become. The new cushions felt new....and firm. Less rolling around for your passengers in corners..etc. Having that experience, I would think you would want to bring the cushions back to OEM specs - by either adding foam or replacing it altogether.
