God, I hope not.
This series, and this version of Batman, should stay as far away from the very concept of Robin as is physically possible. The idea of a kid sidekick was barely acceptable in the 40s, 50s, and 60s. It's absolutely anathema to Batman now, particularly this incarnation of him.
In fact, if I were one of the writers, I would include a scene in the second movie set at a circus. In this scene, an entire family of acrobats--including the pre-teen/teen son--would be killed. I would include this scene purely as a way of telling everyone "Not gonna happen. Not making that mistake again."
I just cannot see any way in which the presence of Robin wouldn't detract from this version of the Batman mythos, or this portrayal of the character, and I would have to seriously consider if I was even willing to go see a Batman movie that introduced the character.
