Sure, why not!? Good idea. Websites can get funding based on ads & hits, and there could be all sorts of non-designer advertising in such a magazine: for e.g., beauty products, shoes (perhaps), mainstream (or highstreet) brands/stores, like topshop, madewell, zara, etc., musicians, artists, writers. Etcetera. Lots of people might be interested in advertising to support emerging designers and avant garde talents - why not?
