There are many.
There's http://skyrim.nexusmods.com/downloads/file.php?id=6027, http://skyrim.nexusmods.com/downloads/file.php?id=10171, http://skyrim.nexusmods.com/downloads/file.php?id=10410 and http://steamcommunity.com/sharedfiles/filedetails/?id=10722&searchtext=dragonbone to mention some.
Those look like poop
Davnat's is just re-colored orcish Wulfharth's and Dagothball's are plain, and aeonvita's looks too strange.
Maybe that's why they were scrapped. Ebony, Glass, and Daedric looked so special, but dragonbone would look plain/ugly and not epic enough to be (most likely) the most powerful weapons in the game.
But if they can do a good enough job, I want a weapons and armor pack that both you and NPC's can aquire. Mithril, chainmail, chitin, adamantium armors and weapons, along with dragonbone weapons.
