Anyway to change the dedicated buttons style?

[Flagz]

One of my biggest gripes about my LG G3 is the on screen buttons. I wanna make Eminem more low profile but don't wanna ruin my home screen (Standard LG). I tried launcher and it's great customization but I hate the look of it. Not one launcher stood out to me so I wanna keep my LG G3 skin but just change my buttons to an Android L style. Any possiblity or should I just throw in the towel?
