Magnetic chrome car letters

Car Word Magnets called for magnetic bumper stickers, which is a great idea. I couldn't find a category that seemed right for this, but bumper stickers seemed like the closest fit. This idea is NOT for a bumper sticker.

This idea is for a set of those 3D chrome letters found on the back of almost every vehicle produced in the USA (can't speak for other countries). You know, the ones that display the manufacturer and vehicle model, like "Honda Odyssey LX" etc? Well they sell tons of such kits online and at every auto parts store I've been to, but ALL the ones I've found are adhesive.

I think it'd be really cool to have a set of magnetic ones so you can change them up whenever you want. I thought about the risk of theft, but I think that's minimal because nobody would know or expect them to be magnetic. The biggest risk is losing them in an automatic car wash, so you'd just have to get used to washing your car by hand, or removing the magnets before entering. The good thing is they'd just stick right back on afterward without loss of adhesion.
