Alternative: or if all the GravityBox tweaks are already in that ROM

Firstly Gravity Box generally does not conflict since most of the ROMs for the N4 are based on AOSP/CM !!
Secondly you could try HK Theme Engine Xposed module to get themes for your phone. http://bit.ly/1jXkwxc
Thirdly : You could try LiquidSmooth/Mahdi they are fully feature packed ROMs !!
