SIII Soft Plastic Battery Cover?

I got so used to the feel of my Nexus 7. I think a battery cover with a similar (or the same exact) texture would be great for the Galaxy SIII. Not a case, but an actual replacement battery cover. This phone is damn slippery, and I almost drop it all the time.

Does anyone agree? Does such a thing exist? Should I start a kickstarter campaign to get one produced?
