If a crew has got to this juncture without any action or intervention, then they are out of the loop. It’s too much to expect a timely recovery from a self-induced scenario: they were unable to diagnose a nose-high reducing-airspeed situation while it was happening, which often has a simple remedy, so what are the chances of correct recovery action being taken? Not good. We’re not talking about test pilots exploring the envelope, it’s line guys well out of their depth, for whatever reason (distraction, fatigue, gradient. etc.)

Possibly better to deal with the incipient low speed event with elevator and trim if required, maybe with an “I have control” in there somewhere. Unless something has actually broken then rolling to contain the pitch shouldn’t be necessary; you have it as a last resort but it’s going to look awfully odd to the guy in the other seat unless you’re very quick with the explanations. Plus, if you have the skills and gonads to throw in 60degs of bank at low level why the *&%^ didn’t you do something less extreme earlier!?

Report following is remarkably similar to the FlyDubai 737crash sequence.

On 24 December 2015, the Interstate Aviation Committee released their final report stating that the crash was caused by an under-qualified crew who lacked the skills to recover from an excessive nose up attitude during a go-around procedure. The go-around was necessitated by a positional error in the navigation system, a map drift. The pilots’ deficiencies were caused by lack of airline safety management and lack of regulators’ oversight.[24][25]

According to the final report, during the final approach the crew initiated a go-around, but being under high workload, which possibly caused a "tunnel vision effect", they did not perceive warning messages related to auto-pilot disconnection. When the plane climbed to 700 m, its pitch angle reached 25 degrees and the airspeed dropped to 230 km/h.

At that moment the captain, who never performed a go-around before, apart from the training, moved the yoke, pitching nose down, which led to stopping climb and started descent and increase of the aircraft's airspeed. After reaching the altitude of 700 m, the aircraft started a steep nosedive, with the pitch angle reaching −75° when the aircraft impacted the ground. The plane crashed on the airport's runway with a speed exceeding 450 km/h. The time from the start of the go-around maneuver until the impact was about 45 seconds, including 20 seconds of aircraft descent
