Default [Q] Would this method work to give KitKat themeable batteries?

I just stumbled across this thread over on the Note 3 forum, and was wondering if anyone has tried to do this on one of our KitKat ROMs?

I'm a photoshop jockey...and I barely know how to jam custom battery images into themes I like and make em work, so this is totally out of my league This, of course, means that there are probably a hundred reasons why it won't work that I can't even fathom.

ROM iiiiixxxxxUm...what day is today?
