No.  Too hot.  The media would slaughter him for it and claim Rudy was put there to create evidence, not clean house.  Best if Rudy stays on the outside and continues to play the role he's playing -- which is out the criminals publicly.  He'll name someone he trusts on the inside as the temp head until he nominates the replacement.    I'd say Whitaker, Sidney Powell and DiGenova would be on the short list.
