The Doctor - Alternatives

What if the incarnations of the Doctor had been played by other actors / personalities...you know, sort of the same but sort of different. Here's my choices :-

Doctor One - Tony Benn

Doctor Two - Ringo Starr

Doctor Three - Kenneth Williams

Doctor Four - Peter Cook

Doctor Five - Bonnie Langford

Doctor Six - Rik Mayall

Doctor Seven - Rab C. Nesbitt

Doctor Eight - Stephen Fry

Doctor Nine - Yosser Hughes

Doctor Ten - Eddie Izzard

What do you, the viewer, think?
