Default How to theme a TouchWiz 4.3 based ROM to look as much like AOSP as possible?

Is there any way to theme a 4.3 TouchWiz ROM to look like (or similar) to AOSP? I've been using JellyBean's ROM, which does this natively, but that is 4.1, and I'll be moving to a ROM based off the new official 4.3 release.
