So where will this series go next? Historical Confederate or movie Confederate? Nothing movie related is springing to mind.
Sometimes DID will just use a celebrity sculpt, but diverge with the uniform and equipment. In this case they definitely based the figure on Costner's Dunbar as they gave him his cartridge conversion Colt 1851 Navy. I think the Thuer conversions were only done after the war, so DID diverged from history.
