Except there is a huge gap in your theory. Percy doesn't learn about the Doors of Death until after The Son of Neptune and he hasn't really had any breaks so far, leaving no time for him to meet Carter. If this story did take place after the war with Gaea, then the Doors of Death would be closed. If it takes place after HoH, but before Book 5, it wouldn't make any sense for Percy to be in Long Island as Gaea and the Gigantes plan on destroying Olympus in Greece
