No, as Kayaba said it, you can't bring the dead back.

The only reason why Kirito and Asuna survived was because Kayaba wanted to have a chat with them. As he makes it very clear, he is awfully interested in those who overwrite the system. If they hadn't cleared the game, one can speculate they would die after the chat, but since the game was cleared, the restriction was lifted to initiate the log-out process in the first place.
