More likely they would die in the shell, or one would absorb the other. You can certainly try, but be prepared to have it fail. You'll have to figure out what to do to help the twin that can't reach the air sac, if they get to that point, because otherwise it won't be able to breathe.
I think there's a thread or two on here of people deliberately incubating eggs, and I don't think the principle is any different for ducks than it is for chickens. Except maybe slightly less risk of injury from pecking each other if they manage to develop far enough, what with ducks having rounded bills.
