Ah, testing the waters huh? I see. By the way, are you going to be running that game at GenCon? I might be interested.
That said, you'll want to be very careful about trying to publish a d20
Council of Wyrms. The entirety of it is WotC's Intellectual Property, even the name "Council of Wyrms". Things such as place names, names of deities, and possibly even the campaign history, all belong to WotC, and publishing it yourself would bring their wrath down on your head.
Also, like I said before, its not that hard to play a dragon yourself now. Special rules for doing so aren't needed as much in Third Edition as they were in Second. While
Council of Wyrms does have some mechanical aspects that are as-yet unconverted to 3E, these alone don't seem like enough "crunchy" bits for a new release, which should have plenty of crunchy goodness. It also doesn't help that the things that have mechanics are also WotC's IP (I think).
You're best bet is to try and get a license from WotC to produce a d20
Council of Wyrms, but that seems unlikely to happen. Even if it did, WotC would almost certainly insist on being the publisher themselves, thus taking a large portion of the profits. You would get paid as a writer, but wouldn't see continual revenue from sold copies.
And of course, just being a publisher yourself can be expensive and difficult.
Here are some pages with more information on these topics:
http://enworld.cyberstreet.com/showthread.php?s=&threadid=33037 this thread is a FAQ all about d20 publishing.
http://wizards.com/D20/main.asp?x=welcome,3 this WotC page has information about the d20 License in all its forms. Be sure to check out the sections under "Official Licenses" and "Official d20 System FAQs" as well as the SRD itself.
http://opengamingfoundation.org/ and of course, the homepage of the Open Gaming License itself, which makes the d20 License possible. Not every game out there must be d20. Some, such as the
Everquest RPG and Monte Cook's upcoming
Arcana Unearthed are pure Open Gaming License games, with no d20 Content, though they're still 100% compatible with D&D 3E.
Hope this helps!
