Manga that needs a new anime adaptation

Several anime adaptations have been made out of existing manga, some of them unsuccessful or too short.  What manga would you like to see have a second chance as an anime?

RG Veda- This long fantasy series was only made as 2 episodes.

Outlanders- A short OAV that captured some of the mood of the story, but not enough. 

Dragon Knight- Way too short, loosely based on the RPG series.  Could have used a longer story with more humor, sex, and drama.

Hellsing? Hell no. There's no f'n way that even japanese would do Hellsing without butchering it beyond recognition... AGAIN.
It's way too violent for TV, and it's too long for OAV.
