That's the way I'd do it, because that fat wire gets expensive and there is no tangible benefit I can see to connecting N-G in both boxes.  Both neutral and ground get connected together in your main box anyway, and I personally would rather have a single point ground-neutral connection to avoid any possiblity of ground loops.
