Community of artists vs One artist and implementers

I am back from the Willow Creek Student Ministry conference. There is always a ton of info to be processed coming out of these things but something jumped out at me right away.
A little background first, I hold leadership meetings for my volunteer staff every other week. A while back, I made the decision that these meetings would include very little planning, instead we concentrate on catching up on each other's lives, prayer and a little leadership development stuff. They have worked great. Unfortunately, in this effort to protect my volunteers time, I have all but eliminated them from the creative process of communicating God's truth to our students. In other words, I come up with a brainstorm or brain fart depending on how it works out and then ask for their help in executing the idea.
While at willow, they pointed the two kinds of programs they run. 1) The program where the team, a community of artists, has caught hold of a specific creative idea and each added to it and made it an amazing thing vs. 2) The program where one person has an idea and everyone basically does as they are told or asked.
Our programs have fallen under #2 for too long. The challenge is this: How do I include my volunteers, some of whom are the most talented individuals I know, in the creative process without 1) adding another meeting to their schedules 2) harming, what I believe to be effective leadership meetings?
I am perplexed and excited all at the same time. I don't know how to make this change and but man what God might do through all of us together...
