I've been in a steep decent on a 27 from what I would guess to be about 10K(I wasn't in the cockpit so I don't know for sure) but to attempt that from 32K I don't think would be possible without loosing some vital parts of the aircraft. For one your IAS dosn't truely reflect the true the speed of the aircraft that high up. I'm not a pilot but to slow the aircraft down enough at 32K to deploy the spoilers you would most likely stall out.
