So we have long wondered if we can get rid of TouchWiz altogether. Maybe you already knew this but I didnt. So despite the fact that this linked thread below is like 6 weeks old apparently I missed it the whole time till today.
Replacing stock launcher - xda-developers
Bottom Line: Copy LP or ADW .apk file [com.fede.launcher.apk for LP] in data/app and paste in system/app. Then in system/app rename the TouchWiz30Launcher.apk to TouchWiz30Launcher.old. Reboot. Its literally a 35 second process in RE. Took longer to reboot and than to copy and paste this.
The most notable change to getting rid of TW is when you go to put a new shortcut in your LP dock, it usuallly take what 10-15 seconds for the app list to come up if you pick Apps right? Now its instant. Everything else seems as fast or faster than before. I for one am glad I made this move. I do recommend this to all using LP or ADW. If anyone still does not have RE [Root Explorer] its well worth $4 or whatever it costs thesedays, you cannot do this with Astro.

Also on a semi-related note I have uninstalled AutoKiller as well and am seeing how I do without it. But thats another matter.
