If we are only dealing with scratches on the plinth, this is mostly cosmetic and might be resolved like Markd51 has suggested, with another and much improved plinth. Built using your own specification or even with help using info from the net and here. With improved materials, looking and much improved then original. I would also look into if you feel like keeping the original plinth with contacting a plastic and acrylic store to see if they have a solution to this. I for one would keep the Aries and work towards an improved version.
