An army of artists, writers, gameplay directors, and testers means absolutely jack without a slew of dedicated coders to tie it all together, and most coders are more sensible than to take on an overly ambitious project like this with people who know nothing about the actual process of game design.

Basically, I think you're aiming your sights too high. MMOs aren't exactly the easiest things to construct with a ragtag team of people online. If you'd like to take on a project without any prior experience, try making an RPG Maker game with your team. Trying to jump ahead to something advanced like this, though, is asking for failure.
