I don't think this is viable. Let me throw another hypothetical scenario at you that has a similar theme:

Let's say you bought and paid for a Babe Ruth single signed baseball from an auction house. The auction house sends you the baseball, but it's not authentic. The auction house offers you a refund so that you're made whole, but you insist they send you an identical authentic Ruth instead. And then sue them for damages related to a future sale of the valuable baseball, which you now aren't able to sell.

I don't think that situation would end well for anyone. I'd neg the seller and forget about it.
