I don't understand why everyone thinks Mayuri is going to "fix" Zangetsu. There's nothing wrong with it, Haschwald just broke it in half because he was more powerful at the time. It'll reform itself eventually. Objectively, Mayuri might suspect Ichigo's Quincy heritage, which would make him quite the test subject.
