Someone already took venture Bros. So Bleach. They often add fillers that differ from the manga and have no relevance or meaning to the main story (which of course is really annoying, altho they've been moving forward lately.) So its ironically a reimagined "old" cartoon/anime that's being reimagined as they write the real story. Because of the delay in the manga being published. Actually now that I think of it, it seems odd that a cartoon/anime can be animated faster than a manga.
