I'm reading some guides on how to build my own ROM, but in the interim I'm wondering if what I'm looking to do is even possible. I came from a Nexus S 4G and had a completely bare-bones ROM (SlimICS). I want to do something similar, the intent being to completely remove all traces of TouchWiz. I want to know if this is even possible, if it's been done, and if not I want to know what the issues are. Also, links to any sort of guides are greatly appreciated.
