I'd be extremely hesitant to do this, especially given the amount that this may be. That being said, my girlfriend successfully disputed a Paypal charge on her AMEX relating to a purchase of a fake Gucci purse on Ebay. Paypal wasn't too helpful, but AMEX was.
I would just use amex to pay your merchant via paypal. Then if something happens, file a dispute with amex.
