Then it's more like a Gimli / Terceira scenario, but with some little thrust available and full hydraulic. All about managing the drag out at the right time to reach but not overfly the 12000 feet runway ... I believe the crew would have loved that challenge compared to what they had to face.
In any case I would find an actual study of glide performances - and subsequent recommendations as of how to best manage it most interesting. Be it bird strike, fuel leak or incomprehensible ice creation there have been a non negligible count of cases where a modern airliner had to glide. As far as I can tell these are so far considered exotic circumstances and not trained in sim or even mentioned in performance charts. It might be worth (re)visiting.
