Does the planning consider continuing the flight at 10k altitude with uncontained engine damage possibly causing a fuel leak in one main wing tank? That could be a loss of several thousand pounds of fuel plus significantly higher fuel flow from low altitude, single engine ops, and higher drag around the damaged nacelle and past the busted-out window.

I'm not sure any aircraft doing ETOPS would fare well in that situation. That's one reason why a single-blade shedding event is supposed to remain contained, as part of the original certification process.
