How about a little taste from MIUI v6 ?!
Xiaomi Member Sunny has made a great theme for MIUI v5 that gives you the look from the new OS! Not all Icons are themed now but it gives you the transparent Notification Area and the flat system Design! So give it a shoot , you will like it!
To install this theme: open thememanager and import the Theme from your location where you have saved the theme.
