I've seen a pic of this a done a while back, but can't find it now... I'm thinking about moddifying a euro plate, to (legally) accommodate my MA plate (front). Basically, would have the US plate in the center, with the euro cut on either side. Any thoughts? I do realize the US plate is about 1.5" taller.

 

Check this out. Maybe you might just want to leave your euro plate on and if you ever get pulled over hit the retractable license plate button and then you will have your U.S. plates on. Just a suggestion.
