Gatherer has a copy of the Wowhead db that it can import. So, if you make Carbonite compatible with Gatherer, you'll also have access to every node that Wowhead has tracked, which would probably be a huge time saver.
Hopefully, it's not too tough.
You can download their main db to check for compatibility here:

That would be very very cool if it worked.
