Just use drop pod technology; some jet fighters have AFAIK disposable under-wing fuel tanks.
Only dropping one that self-tests to high enough confidence/quality, and using e.g. GPS or laser guided bomb technology with a parachute and catch net at the landing site:
With a good net you can drop a human in a wind proof ski-suit (cold air!) and with an oxygen bottle from the Armstrong limit where their blood starts to boil, something like 18km, notably without a parachute.
So it will be easy to catch a pod that falls sideways on a drouge chute to trade off parachute size (weight!) and net height/give.
