This is a great concept. I like the Porsche etching. I removed my cup holders during a radio installation and now I have an upper cubby to fill the gap. I'm currently using this seat wedge cup holder style. It can be stored in the back of the seats' pocket when not in use. It holds all types of beverages but I use it mostly to put my cell phone and keys in. Perhaps this can inspire you on your final product.
The flaw in this seat wedge style is it takes away space for the passenger seat when in use and the back of the cup holder isn't padded. I recommend using foam padding tape on the back so it doesn't scuff up your center console if you go with the one I'm using. It's like $5 shipped on eBay.
