I have to agree here. The frame might give a little added protection for the camera equip but in the long run a tripod is going to be more useful.Are you sure you would want to do that? I can't imaging a bag with a ball head being anywhere near as flexible as a good tripod.
For instance, if I were using a bag like the way you describe, for the shots below I would have had to submerge or sit the bag down in water. Even if you're only working in dry climates, I can't imagine a bag being very good for anything but straight up and down, flat land shots. Seriously, don't leave the tripod out, you may regret it.
