Okay, here's the one of the few ways I really see this working.
We use Batgirl's basic origin for the intro to our (for lack of a better term "sidekick"). While not necessarily Barbara Gordon she beats out any of the Robins purely because I've seen too many father-son relationships and not enough father-daughter, plus I want to see Hit-girl/Big Daddy done seriously. Now, from a story perspective, Batman needs an external force to lift up out of the crap that TDK left him in and no one currently in the series is in any position to do that.(Alfred is a lying to Bruce about Rachel, Fox is on his way out, and Gordon is under siege from his own corrupt police force and is hunting Batman) That's where our "sidekick" comes in. They bring in some light hope and happiness into the Batman's nightly prowling and, most importantly, can actually be threatened. I mean, let's face it, Batman is so physically capable (beating down BOTH SWAT and a gang at the same time with no human deaths, taking bullets to the gut, kidnapping a VIP out of China) that nothing can really threaten him in the eyes of the audience, but an untrained and untested sidekick would be in actual peril in even the simplest of scuffles. Batgirl/Robin would be independent of Batman, making their gear from scratch and writing their own rules. Batman catches them several times but never convinces them to stop and they slowly warm themselves up to him. For an actual example of how this would be done watch the entire third season of The Batman (the post-BTAS with slight anime stylings). Basically shows the evolution of Batgirl from annoying and in-the-way to independent a capable hero.
The villain would have to be one of Bat's ladies since he needs a good replacement for Rachel and their are no good gals to really pull from. Catwoman's simple thief who doesn't really hurt anyone could work and we all can imagine that. Drop the previous affair and possibly her daddy's name and Talia 'al Ghul also works by bring back the League of Shadows. And pair up perfectly with her would be Poison Ivy. Of course, Ivy would have to be reduced to a very pretty man-hating eco-terrorist lacking any actual powers just some potent chemical and biological weapons and a massive desire to use them on Gotham. Rounding off the possible villains are a Riddler played by David Tennant (not Depp, we want quirky smart not insane gibbering), Penguin as the new boss of the underworld (played by Phillip Seymour Hoffman), Black Mask basically lifted as is from the comics, or a much more cerebral Bane (think Joker smart and physical equal to Batman). Hush, Mad Hatter, Zsasz, and other relatively normal bad guys require a little too much back story or lack the appropriate dramatic gravitas to really work for a whole movie. On a side note, that Robin origin movie idea would match up great with the likes of Calender Man.
Basic plot goes:
Batman running around getting beat up barely holding the city and himself together
Batman inspires sidekick to become hero
New villain shows up an attacks city
New sidekick builds up skills and tools to start off with (Think compressed Batman Begins)
Batman and sidekick meet, Batman disapproves
Villain attacks in earnest
Sidekick proves self to Batman as a better writer with more time takes villain vs Batman vs Cops to whatever conclusion the Nolan's want to bring it to
