Just a random idea for someone with a bending brake and a sewing machine to try...
Mill yourself a normal back-plate, but without the channel for the wing-nuts... Just a plate, with a bit of curvature to conform to the shape of your back, and drill holes around the perimeter.
Cut double-vertical-slots in the center about where the normal mounting bolts will go. Thread cam-bands through these slots.
Now take a normal wing of your favorite size, take the bladder out of the outer bag, and sew little tabs with grommets through them to the perimiter of the outer bag.
Re-insert the bladder into the outer bag.
Now tie-wrap all the grommets around the outer edge of the bag to the holes in the perimeter of the plate.
Voila; backplate-type advantages, but without the STA and trough that push a single-tank so far off your back. And with an additional advantage that the bladder won't "taco" around the tank. Of course, tie-wraps aren't exactly removeable, so you lose some reconfigurability, but maybe someone else can come up with a good detachable / reattacheable way to fasten the wing to the plate that doesn't involve bolts or other projections through the plate that could dig into your back.
Not that I've ever tried such a thing (or even a regular BP/wing), it just seemed to be an answer to one of the issues someone raised for using a bp with a single tank.
