Joe Johnston is my number one choice for an Episode VII. Many people could probably capture the spirit of the original trilogy, Johnston definitely would.

For those who don't know, he was a concept and storyboard artist on the original trilogy. He also directed Captain America, which on my second viewing I realized was far more Star Wars than any movie set during WWII has any right to be.

I'd be tickled by a Brad Bird take as well.

That's a great list. Although I think that Brad Bird would be a natural choice as well.
