I can't guarantee it but I don't think so because there where a couple of exploits in the past for the porpose of creating dubes(all fixed) you have to trick the server to do it and I think they will notice it very fast because all Item have an ID that is unique on the server this way they deleted the last dupe wave only those whrere came out of the magic box remained so far I know.
You can try to do something with this magic box but you have also trick the client and the server.
there were in past but they fixed everything and banned ppls who made them and removed them so ppls got pissed off badly coz of the lost runes but after some months of investigation they sended them back to the ppls that bought the duped runes
