Small rivet (wheel) orphan

I've spent 20 years thinking I had a cool set of factory alloys on the Bronco.
Turns out one of these things is not like the other....

So I have a small rivet 15" that I'd like to ideally swap for a large rivet.
But I'd rather find it a proper home than sit on it for another 20 years.
Picture looks horrible but those gashes are superficial.
Rim is true and is holding air still (hasn't been on the truck for about a decade).
I'm in central Georgia.
