Anyone out there want to trade wheels? (17" for 15")

Today might be the day that I get my Prius. It better arrive.
The idea of eventually upsizing to 17" wheels has been on my mind.
All of a sudden, I got the sudden inspiration to ask around if anyone
out there with a set of new (or almost new) OEM 17" wheels and tires wanted to, for whatever reason, downsize to the 15" wheels and tires.

If you happen to be in that situation, let me know!
I'd be willing to do a trade with an agreeable amount of cash in addition.

I know that the 17" wheels will cause a slight MPG reduction, which wouldn't bother me. I'm hoping that someone out there maybe doesn't care so much about the wheels and would also rather pick up a few MPG, along with the softer ride.

I realize that this is probably a shot in the dark, but I figured that it
would be better to at least shoot while the tires and wheels are brand new and unused.


edit - If this needs to be moved to a different forum, sorry.
I didn't see that "marketplace" section before.
