It would be much more interesting getting a total newbie and follow their learning curve. I think you could find it easier to produce a film in short multi day hikes. The logistics of a cameraman with all of his camera gear and top that off by the fact he too has to "backpack" with whom ever they/you follow would be nearly impossible. Batteries alone would be a major hurdle, unless of course you have a mule team following the crew around. Sounds like a disaster if you ask me.
