Damn, I think that really looks great! I wish there was a way to get a "magnetized" skin ..... I use a magnetic car mount, and keep the magnetic-disc in the case. Would love to ditch the case and go with that skin!
I know that feeling

I'm almost never using my phones without a case, and I was using Ringke FusionX case with a clear back with my phone now. It was alright, the pattern is mostly visible but still didn't have the same look and feel, and I don't like the way clear cases get fingerprints all over after a day of use...
I wanted to experiment and see if I can use the skin on the case itself... Ordered some extra skin, traced the shape of clear portion of the case on the backing paper on the back of the skin and patiently cut it out and... viola!
I'm using it for two weeks without any issues, the raised edges on the case make sort of a "frame" the skin can rest in so I've had zero issues with dust and pocket lint...
I think it looks great, feels very nice and grippy, doesn't have any problems with fingerprints,...
maybe you can even use this combo with your magnetic disks inside the case and use it in your car...
