I use one like this for my small pack.
I absolutely love mine. There's lots of straps to hang layers off as you adjust to temperature changes. There's plenty of room for anything that fits in the fanny pack. The hydration pack fits in really nice. The chest and waist straps keep it in place when running and it has a profile that easily fits within the width of the shoulders to make moving through trees and brush easier to do without snagging.
If you still wanted a little of the accessibility of a fanny pack, I've seen detachable pouches like the MOLLE web gear style that could be attached.
It's not as versatile as the one that you've posted, but this would be a good replacement for a fanny pack. It will hold all of the things you listed and has the hydration pack. It's truly amazing how densely they can be packed!
I'll see if I can scare up some pics of mine.
