No it's not sorry. As I said it's a massive change to pool code to fix just one address of yours and without a message signed with your private key there is no way to confirm you're the owner of that key even with old posts from the forum. it's no different to withdrawing money from an exchange with your address; they would never give you the money to a new address without you confirming you're the owner of the old address. This is no trivial thing you're asking.
