For the CF6 on the 747, initial procedure for a stall is to reduce thrust until it stops, to idle if necessary. Then, bleed air switch off. I would likely stop there on short final.
I actually had one do this at about 700' on approach to HKG at night. F/O was flying, so I simply pulled back the thrust lever on the affected engine with one finger after telling him I was going to do it. He continued the approach without missing a beat. Good news was that all the turbine parts that had exited the nacelle did so over the harbor, and the runway was clean...
FWIW, that one was on a Classic, so the FE may have done the bleed air thing, but I don't remember the details. The EGT spiked after landing, so we did shut it down on rollout.
