Why not make a mod to change the durability of blocks? That way creative servers don't have to band ores, obsidian, and brick do to their griefing potential, they can simply set bricks to be as soft as smoothstone.
are you requesting a mod that destroys every block when hit (insta-destroy)? I have one running on my server, but it ignores every block, so you can destroy bedrock etc, but i can make it editable...
