What you are joking about is in my opinion much more serious than it looks like at first appearance. Why do you think so many rich people love to spend lots of money to have e.g. buildings named after them (for example at reputable universities)?
So your suggestion, of course refined gallantly in a way that makes it presentable in polite society, does not sound that absurd to me.
Considering the etymology and historic origin of "artist" as a skilled artisan. It's not even that novel an idea. Lots of things we consider art pieces are named after the buyer and not what we consider now the artist.
