I'd love to see Stardust turned into anime. The world-building lends itself to being translated into a visual media, and while I loved the feature film (warts and all), more versions are never a bad thing. And in the vein of Madhouse's Supernatural anime, I think The Vampire Diaries would translate really well. It starts you off thinking it's going to be the worst Twilight ripoff, and then turns around and becomes creepy and tragic and amazing.
