I've made a full expansion for Defenders of the Realm, based on Monty Python and the Holy Grail. This has not been playtested fully yet, so if you have any questions or comments or suggestions, by all means, let me know.
The PDF file with everything is here: http://www.mediafire.com/download.php?o77yab5t9g4u1lp
Individual graphic files are here: http://s746.photobucket.com/albums/xx107/Grudunza/Monty Python and the Defenders of the Realm/
Artscow deck which includes the regular-sized cards for this expansion (and cards for some other Richard Launius variants): http://www.artscow.com/gallery/card/defenders-of-the-realm-variants-fg1hjehlx0vc
