Well, right now, it breaks out as follows:

Ditch kit: ~7 pounds, mounted in a chest harness w/ 1 liter of water

BOB (summer configuration): ~40 pounds, in a frameless pack w/ 4 liters of water and five days of food

Winter add ons add about 22 pounds. Approx 16 pounds is tied up in my old, early 80s vintage, USGI surplus arctic bag.

Along with a new pack, I'm planning on replacing my cold weather sleeping system. I can cut half the weight of that using modern materials. I've also got nylon tarps that are going to be replaced with tyvek, which should save me about four pounds.

The configuration I'm looking at will take the sleeping bag out from under the bottom of the pack. I know from experience that, at least to me, adding 10 pounds onto the weight of the pack proper takes less out of me than having 5 pounds in a dry bag slapping the backs of my legs. So if I can get my load to stop playing grabass, I can manage the weight better.

It is not going to be a small pack. I'm the first one to admit to this- between BOB, the ditch kit and the small pack, I expect to have about 10-12 pounds added after swaps for lighter gear, half of it in water. It isn't designed for ultralighters, although I am going to be incorporating some of their gear. My basic plan has always been a day+ of water, 3+ days of food; I'm at 5+ days of food, and I want to get to 2 days of water. I've got plenty of water options on my main route, but it is one of three major East-West roads in the state and most of it is down stream of either old quarries or farm land, so I'm always a little nervous with it.

And I do intend to field test the load. If it is too heavy, the small pack idea gets discarded and the bag for it gets sold off or retained as a day pack. But once upon a time, my gear ran about 65 pounds total, in the summer, and that was packed into a stock ALICE pack, frame and pads. I road hiked that beast once on what is now "route one" for me. With this rig, I plan to do it again- dry run for a bug out on foot by main route, complete with two anticipated way points for sleeping. (And one is programmed for the first night, so I can dump and reorganize gear with a friend if I have to.)
