@hazardwarning The one on my current backpack could be slid up or down in about a six-inch region to help with that. I'd totally believe it still wouldn't work out though. Bodies come in a lot more shapes than the stuff we try to strap to them.
I'd probably struggle with a waist strap because all my weight is around there. Mostly wear stuff at the hips instead.
