ROFL...
Ok, having picked myself up off the floor...It's not impossible ( I guess) but given that "Flight International" has carried reports of BA finding a buyer for some of it's 757s this Winter, and the BA BALPA Reps are manfully trying to help organise moves for possibly displaced pilots from the 756/767 onto, say, the Airbus, I would hazard a guess that this rumour is not true.
