Sure. But wouldn't it be nice to have three eight hour shifts, instead of two 12 hour ones?. Or back to back 12hour ones?
Then there would be less duty time problems, and more stable rosters. And a little fat, in the system,so that an extra night flight can be flown at short notice sometimes without major disruption.
I guess, if the money is not available, then it cannot be done.
But, if this is the case, then the notion of two pilot crews is just dreaming.
