Consider taking no camera at all. I've never been into the wild and taken a picture that was anything but a disappointment compared to actually being there. Furthermore, if you want to show your friends any of your images they will only be interested in the ones with people in them and capturing a portrait in the backcountry that pleases you is almost impossible compared to what you might think while setting in an armchair at home.
Most pleasing landscape photography is done by people traveling directly to the site (usually by car), at the perfect time of day and year, with the perfect weather and without the time constraints imposed by a backpacking trip. Backpacking and landscape photography are equal avocation, and are best practiced separately, in my opinion. If anything, take a P&S with fill flash for group shots.

Oh dear. That's hardly funny, amusing or correct, what you have actually written suggests a lack of skill, discipline, drive, enthusiasm and the capacity to blend two enjoyable pasttimes. Backpacking and photography go
together, not separately, and the best places can only be reached by going quite literally off the beaten track—on foot (of course a car is used to transport you to the start). Bushwalkers have been doing this since Nelson lost an eye! The original OP had a good list of equipment that he wanted pared down, and we answered based on what is common and sensible (many bushwalkers do take more than one camera: I have a Russian colleague who takes a Nikon digital and a Hasselblad 503CX with flexbody). Further, I can guarantee that well-executed photography, be it landscape, wilderness et al, has a good and receptive audience — and buyers, too — but it must be produced up to a very high standard, and your reputation will be made on the foundations of how much quality and effort you are putting into both getting "out there" to the subject and bringing the subject back skillfully in photographs—irrespective of perceived "perfect time of day and year, perfect weather etc.", none of which is true in reality. We learn to photograph well in
all conditions.
