Hmm, I really don't know what to think.
I mean this kind of flick is definitely something more suiting to his style (Planet of the Apes was not a good fit for him), but I love the original so much that it would be hard to redo.
Personally, I don't really see Wonka as a children's movie. I'm mean sure on the surface it does... but this movie scared the shit out of me as a kid. I was afraid of Wonka. Thankfully now I'm over it and can appreciate the movie
