Default Android L Icons question

I am running Cloudy Stock and was wondering..... Is there any way to make my navigation buttons look like Android L? I've tried a soft keys app and some Xposed module that supposedly allows you to theme using a cyanogenmod theme but it was not what I needed. Any thoughts on how to do this? I don't really know how to decompile framework and and all that. Or have the time for that matter so I was looking for something relatively easy if such a thing exists haha.
