Yes, but if there is a serious desire to get a new journal off the ground, I would suggest starting with a set of business practices around reviewing that will give the "academic respectability" required by many universities. Then expand (rather than change) the modes of publication offered by the journal to incorporate/experiment with new approaches. I think being too radical in every spect initially is likely to make the project too high risk to gain support.
