Default Touchwiz themes

Hi is there anyway that I can put a different theme on top of another rom? I'm about to switch to minions on my t mobile s4 from purified i9505 rom and I would like to have an aosp theme or kit kat theme like these in my screen shots below. Is there a flashable zip(hopefully) will I have to go through and decompile the system ui apk?
