Demon Gas Cap custom options/builds

Hello,
I am getting ready to do the exterior paint. I got rid of the side marker lights as I wanted a cleaner look on the sides. But I keep looking at the spin off gas cap protruding out the rear quarter. I am looking at gas caps for 2014-2015 dodge challengers which are a flip top and they come ion a nice black to match the side stripes if I choose to install them later. Just curious if anybody on here has retrofitted a gas cap to give a better look?
