Firefly:
A/c can stall in any attitude and airspeed.
Nonsense.
We are talking commercial aviation here, not aerobatic puddle-jumpers. If you are pulling that much g that you stall with the nose low and with a high airspeed, then the stall-condition is NOT your primary problem.

Anyone remember "step on sky"? Unload the plane to zero AOA and use rudder to level the wings
Yeah, except we don't use rudder to level the wings in commercial jets. The rudder is immensely powerful, especially with twins, and has to be treated with respect.
Let's say the left wing stalls and drops. If you kick too much right rudder, the swept wing makes the right wing violently drop. This leads to the perception that the right wing has now stalled, even though you may actually have successfully unstalled the aircraft. So you kick left, and now the left wing drops. And what you have just successfully achieved, is to do an American Airlines 587, and break your tail off. And it was all one big PIYaw and PIRoll (as opposed to a PIO), and nothing to do with the stall.
The recommended technique is push the c/c forwards (I term it this way for a reason), reduce the thrust a bit, gain some speed, and THEN roll the wings level. Simple and safe.
