Unfortunately no, as the camera requires the TouchWiz framework yo be installed.
You can however use a custom TouchWiz ROM, such as GoldenEye. Performance is better than stock, and it's based off the latest international firmware, so you'll be running a newer firmware that what is offered on AT&T.
If you don't mind losing the TouchWiz camera, then try out the official CM10.2 nightly from get.cm. It offers a ton more performance, has great battery life (I'd say comparable if not just shy of stock), but doesn't offer the same camera frills—oh, and of course, it doesn't look like it could win an award for being so ugly.
Personally, I would try CM. If you can't handle the camera (which is about the only downside, as I didn't end up using any of the gimmicky TouchWiz features after awhile) then it'll be so much better in every single way. If you feel you need the camera, try out GoldenEye.
Good luck! And happy flashing!
