If we want to hear any suggestions or worries chapters may have, I think we should make some chapters-only activity, no matter if we also do something with the broader audience. Chapters are the only officially recognized Wikimedia entities other than the Foundation for the moment. Transforming the chapters' day, chapters meeting or whatever it is called into a more general partners/groups/movement thing would perhaps imply putting in practice our recommendations before they are accepted by the concerned parties. Before that, I would try to guarantee that chapters can express confidently any worries they may have.
