Good dungeon that's longer than the original?

[Stop the Insanity]

Hey. I loved the original dungeon. I haven't even got one mod yet. I was wondering if there are any that are longer then the original dungeon. I'd like to be able to get my characters from level 0 to max level (or close to) in one dungeon. Obviously if I do this, it would have to be a good dungeon. Hopefully as good or better than the original. Is there such a dungeon that can achieve this?
