If a pilot on the ground had checked the telemetry and seen that a) the plane was stalled and b) the elevator was at max deflection, he would have asked why that was the case and the pilot who wasn't in control would have realised what was going on. We aren't talking about giving the flight crew another automated message or bombarding them with unwanted input, just allowing somebody in a more sterile/low stress environment to monitor the telemetry for obvious problems

Sometimes a fresh opinion, or some input from somebody who is removed from the situation, is all that you need to set you on the right track or break an assumption that you were incorrectly holding.

The accident occured in minutes, there was no time for a potential operator to do anything about it anyway. Too many "if" in your scenario to make it sound plausible.
