Well, first of all, The Wind Waker was in no way meant to look like anime. There's a big difference between anime and cel shaded graphics. NOOB

Anyway, I think this would be a horrible idea. Reasons why:

1. There's no point. The Zelda series has always been known for having their own unique look and feel. To make it anime would make it the same as half the games out there. Plus, it just wouldn't fit.
2. Increasingly dark storyline. As time has gone on, Zelda has gone from more than "Save the princess" and has delved deep into the human psyche and philosophy, with their increasingly better graphics following suit. (The exception of this was Wind Waker, in the graphics department anyway. Why they chose it to be cel shaded is a whole nother thread) So, to revert back to such simple and easily done graphics as an anime would not give it enough credit.
3. Just cuz
