We do have that option in the USA... OP is in Florida, I am in PA, right next door to you. Some states require front plates, but others do not, and you can run a Euro style plate there if you want, or even nothing at all (which is what I am doing)
I bet you could move your NJ required front plate to a different location if you want, although I suspect the car was designed with the current location in mind and probably doesn't really need more air flow. Look at the tiny grills on lots of expensive cars with lots more power... I bet that huge grill we have is just for looks... we even have a mustache blocking half of it.
