Yep, AWS has a full setup with the new backpad and harness padding. I've tried it on a couple of times; it's works as described and is pretty interesting, though I imagine for the BAUE crowd its value would lie more in those who may have mobility problems making it difficult to get into and out of a standard harness comfortably.
For anyone looking into getting these for doubles, you want to bring your tanks/wing/v/tailweights in and assemble them on the backplate to ensure it fits - there's a substantially thick plastic bolt-on piece with spacing tabs that might make it incompatible with short bolts.
