I've had similar thoughts and have been trying to figure out how to make it work for a while now. I do a little bit of teaching at the Rockler store where I work part time on the weekends -mostly make-and-take classes and product demos. I also live near, and have taken classes from George Vondriska. (George is the head of the Woodworkers Guild if America, and appears in many TiteBond ads in magazines). It seems to me that if you want a career in woodworking that you can live off of, you have to have multiple streams of income within the industry. So you cannot just simply make products and sell them, or you'll starve. It seems like you have to make products and sell them, teach classes, and figure out a couple of other revenue streams. So, the idea of opening a school and teaching is wonderful and I think that if you also sell access to your shop as a co-op, that would be a natural secondary function of the school that you opened. And that's kind of how I see it playing out, if I ever get to that point. But I've noticed that there are a few co-ops that have popped up in my area recently. (Twin cities, mn) I think that's a really attractive offer to people that want to get into woodworking but get intimidated by the costs of equipment. So instead of paying a ton of money up front to buy the necessary machines and hand tools, they just pay a small monthly fee and have access to the shop. Best of luck to you if you take the plunge and go for it!
