I probably will use either a Maule-7 with bush tires, or a 182 Turbo RG II and fly over the course of two days. If I take the Maule up, I may consider landing on a peak and bivvying for one night. I've got a Private with Instrument, 750+ hrs including 100 hrs of bush flying. The Maule is actually the better of the two aircraft as I can set up for low and slow flight. Canyons are a bit goofy with wind and the Maule handles it exceptionally well. I have one HD digital video camera that I can rig to the starboard side wing strut. and pipe the video output to a laptop inside the cockpit and use the remote control for it. The hard part will be the stills as it will require several passes and a lot of patience.
