The RPG Pundit has started a D&D campaign consisting of the D&D Cyclopedia, Forgotten Realm (Grey box), and my Majestic Wilderlands. His first post lists the various PCs making up the party and there are some great ones including a human Mountebank, Charlie of the Sheen.

It is about going back to the roots of our hobby and seeing what we could do differently. What avenues were not explored because of the commercial and personal interests of the game designers of the time.
