I know the procedure including AP off. There is never any doubt about fly the plane. You did what you could you still don't have reliable ADR. My question is how long would you continue in RVSM air space in this condition? Especially your aircraft being in direct law. If there are no terrain issues would you not like to descend out of RVSM and take your chances? I am not suggesting anything but asking a question.
