Anyone ever had luck getting lender of a non assumable loan to transfer it?

Just curious if in the states that banks are currently in, if you called to say you had a buyer who coudlnt get financing, if the bank would approve the buyer to take over the current mortgage? Has anyone ever called the lender and told them they were going to do a subject-to loan and had the lender okay it? The seller I am buying from has his loan currently w/ wells fargo, if that helps you determine whether or not this is worth a shot to try?
