@mike_hales to clarify, I am using "commons" in the way Ostrom used it (or not just an open access free-for-all), and "federation" in the classic anarchist sense; a mutual aid organisation that coordinates cooperation between constituent organizations, without having power over them. So yes, a "commons of commons" would be the same thing, but a "movement of movements" wouldn't (much looser and less structured eg the broader libre software movement).
