Is it possible to build a “shim” for a male wedding band due to weight loss? : jewelrymaking

I have a Chris Ploof wedding band that’s a gold band with a ring of meteorite in it, I dont want to cut and resize the ring, but would it be feasible to make a silver or platinum (or whatever) “Shim” to sit the ring into so that it doesn’t fly off my finger ?

Or is this just a silly idea?
