Hmm- that would be hard to match all of them up without a lot of reuse of the characters <g>
I was surprised you picked Wile E Coyote for 3, but then I remembered how he kept trying to make his tardis work without the proper knowledge unlocked in his brain, and it kept resulting in minor explosions and lots of smoke, and that really does fit him

and the 8th Doctor as Pepe Le Pew did have me laughing.
But I would have switched a few around -
6 is Porky Pig ...or Marv the Martian on his darkside days
5 is Tweety Bird - the first young Doctor, still able to outsmart his enemies with cunning belying his youthful face
4 ...perhaps Bugs Bunny again, or well ..hm, tho he was often clownish, it's hard to think of any toon that could capture him well enough. Any toon out there, doesnt have to be loony tunes..that comes close enough?
7th Doctor ...hm. Speedy Gonzalez? Jerry? (as in Tom and) What's a good toon who's buddy blows things up for him?
I wonder if the 9th Doctor could be done with Kimba the White Lion. Or maybe Simba- pacifist who fights when cornered, holds himself responsible for the death of loved one, runs away rather than accept rulership/guilt...He's not one for eating bugs, but then nobody's perfect...
