Need urgent help making nav buttons transparent topic

he onscreen buttons take up a ton of space. Is there anyway to make them smaller and transparent? This black bar on bottom takes up way to much room. I know in the past there had been options to edit them under the display settings but I am not seeing such options on any 5.0.2 ROM. (I have tried vanir and liquid smooth)

This is on a Verizon vs985. I am pretty familar with the build.prop if Editting it is a must.

I will even paypal someone money for a candy bar if they solve my delima.
