Tony,
what mics are you running these days? If you have actives and A20S mount, you can get pretty damn small.
For the 722 alone with just mics and a set of cables, you can fit that 722 and mic bodies in a very small eastpack waist bag. That is my preferred bag for the very low profile stuff. No padding but for stealthy stuff I wear it on your belly and I have padding there.
For 722+V3+bat, Mountainsmith cairne is a great solution though you could go with the next size down. I use the cairne for open taping an all my crap fits, extra clamps and capsules, etc. You can carry it like a small case or wear it as a lumbar bag.
