Not convincing sorry.
You possibly missed the bit about "immediately" that is immediately after the, in theory' decompression when the oxygen masks would have dropped down.
There would have been a trail of oxygen masks dangling down all through the length of the plane anyone moving along could grab one have a few breaths and move on unless all the seats were full and all the passengers had put them on.
Sorry I missed the bit about when the oxygen ran out, didnt see how long it took.
The maximum period of useful time as hypoxia sets in after depressurization, in MH370's case, at 45,000 ft, would have been less than 3 minutes. In fact, after around 2 minutes without O2, all passengers and attendants would be at least, confused.
In fact, all aboard would initially have been scared stiff as the plane suddenly ascended rapidly from 30,000 ft or so to 45,000 ft, all would be thinking of survival, how to put that mask on, not rescue, as they'd assume the pilot was in control.
About 15-30 seconds fixing masks in place, at least. Then there'd be around 15 minutes of O2 available, and no-one in their right mind would attempt to remove their life-line of O2 on the off chance that they could rescue a woozy pilot.
After that, if the plane had not dropped to a safer level and re-pressurized with O2, hypoxia would quickly occur and death would result in 30 seconds onwards.
The scenario you envisage of someone somehow 'knowing' that the pilot needed rescuing, (How?) removes their O2 mask, unfastens their seat belt, makes their way along to the flight deck, pausing every so often to take a suck at conveniently spaced, unused O2 masks on their way, finally finding another convenient supply of O2 somewhere and giving it to a (theoretically) unconscious pilot, all the while with no O2 supply,...pilot then revives, brain all functioning as normal, to bring the plane safely down.
That little high energy escapade with a drastically reduced O2 supply would knock out any normal man or woman in less than a minute.
Then he'd die, without O2.
As you pointed out, unused O2 masks would be hard to find if the seats were full, so a no-go scenario
