Traditional parachute from 100K ft?
That won't work. Somebody jumping from that altitude is going to need not only supplemental oxygen, but a drogue parachute to control descent rate and provide stability until the jumper is at a safe altitude to deploy a main chute, at least 15K ft. That would require a barostatic lockout to prevent the jumper from manually deploying the chute at too high an altitude, and an automatic opening feature tied to the barostat in case the jumper is incapacitated.
All that gear exists, and would be relatively easy to integrate, but would need a near military level life support shop with FAA certified riggers/technicians and percision calibration equipment for the barostats and supplemental oxygen. Also would need a significant amount of training for the potential jumpers.
