Indeed, a sequence to consider?
Some things are on your side
No real evidence of 'extreme' turbulence in that area (others avoided it)
Combined effects of Flight Instrumentation/degrading systems AND engines tp diagnose/respond to e.g even higher cockpit workload
You would have to make a case for:
No Maydays, ELT
Inability to re-start lower down
What ACARs tx this would or wouldn't have generated
Are you suggesting the combined effects of lost FI and thrust loss would have created a rapid stall/upset?
Or a gliding descent into possibly worse conditions?
