If someone else became Batman, that person would not have Bruce Wayne's identity or money/resources, Batman's allies/companions, and wouldn't have the past, training, or reasons to do the things he does. Plus Batman in the second movie pretty much showed how much he hated people dressing up like him. In the comics, you have tons of different Robins, but you only have one Batman.
Knowing Nolan, I don't think that's really a possibility.
