While the Bosch is a bad little bastard, I'd almost consider upgrading to a Ryobi 18v One+ impact driver as your rotary back end. It's native to the 1/4" hex head quick change standard, and you already have the converter from that to friction-clutch, and to 3/8" socket drive.
I just gave away a rather nice lockable steel rolly-bit that would have been excellent (if too large, I think it weighed in at 30 lbs empty).
I also _saw_ what you want, which is about 1.5x the size of your existing box, multi-layered, lockable (I think) and had an integrated wheel-handle frame for pull-behind duty. I saw it in the golf area of my local Kroger/Fred Meyer, but I brainfarted it.
I'll be back in there tomorrow, I'll check it out and see if I remembered it correctly.
