Actually such a system is available at DG Flugzeugbau. The NOAH system
works with a compressed air cilinder and a bag located under the cushion in
the glider. It lifts to over the canopy rim and lets you just roll out of
the cockpit

How about the BRS plus an automotive type air bag under your butt that

An air bag under the butt is a good idea - but where?
Between butt and fuselage shell there is not enough space, and I doubt
that an airbag under the fuselage (opening through a hatch) will work
reliably.
