Stranger things have happened, BOAC, so it's possible. I've heard reports from the line of FOs doing stranger things after being empowered by modern CRM. But the Far East, where the cockpit gradients are reputed to be steeper than in the west, it would seem very unlikely. Personally, I suspect the final report will contain a few surprises - possibly something disappointing, like the PF called for flap 15 but forgot the related call for GA thrust, PF didn't notice and then the cows got bigger.
