Madeline Kahn as Blanche

Hey just thought I'd throw this out there. High Anxiety, Mel Brooks's spoof on Hitchcock films was made the year after Family Plot. I read that Hitchcock actually liked the movie quite a lot. Personally, I thought Madeline Kahn was excellent in High Anxiety (as she was in really anything she ever appeared in). My questions is, had Hitchcock seen her performance before Family Plot was made, do you think he would have casted her for the part of Blanche? I think she would have had both the comedy and suspense chops to really take that part to the next level. The seance scene would have been particularly more effective. Not that I'm dissing on Barbara harris - I just think had High Anxiety been made before Family Plot, Hitchcock might have wanted Kahn in what would turn out to be his final film.
