I can’t remember where I saw it but someone posted a picture of a bracket where you push and twist two end bracket onto the grill then you just slide your plate in.
A bit of googling turned up this with plates for 6 or 5 characters listed:

Is that the sort of thing you are looking for?
That’s a shame they don’t work mate
Looking at shortened gel plates too but unsure what they would look....any photos?
I bought them and it cost me £60 from Germany, worst thing I’ve bought in a while. Never been on the car and they only work with metal pressed plates, they need to be ultra thin to clip in (German plates).
I am glad i've just read this, i messaged a lad in germany on instagram about these the other day for a price and was gonna order them, glad i didn't now!
Oh really you don't even get the whole bracket, thats a bit of a joke really! Its a shame because its a great idea in theory!
