would certainly help to build up the larger DC universe.
I think this would be a good opportunity to introduce Robin by having him already exist, wouldn't mind them having Richard Greyson and Jason Todd (The Jason Todd memorial would be an amazing addition to the batcave, and flashbacks to his death could be a cool way to re-introduce the Joker) having already existed, would allow them to go straight into a lot of stories without having to go through the awkwardness of having him fighting crime with a little boy at his side. They'd still have Tim Drake too should they ever felt like introducing a Robin to the mix. they'd also be able to use Nightwing.
