[Q] How to have theme like z3 topic

Hi there, I have XSP pure stock .205, what I need to do to have themes like Z3 with new battery icon on status bar(notification bar) and new navigation bar? I found some themes on market but it said it needs to be rooted, so Its all i got to do, just root my SP and install that themes and it will look like i have KK with all that good looking icons? Thanks.
P.S. I didnt get the answer on help forum so I posted here.
