I think this is kind of what reiserfs did back in the day for small files. Keep them in the tree and share pages with lots of small files. It worked rather well, it's just that the file system had plenty of other issues with reliability and recovery at the time. It was vitally impotant that you didn't store any plain text disk images that contained a reiserfs partition on a reiserfs mount, fsck could decide to merge thentwo together causing unknown amounts of corruption.
