Tracer900.net was formerly known as FJ-09.org. It is a forum for the FJ-09/Tracer with a decent following.
The FJ-09 seems to be another slow-seller on the resale market. I haven't seen cases come up for sale on the forum very often, but you might be able to persuade a seller of an outfitted bike to part with cases to free up some quick cash. Then again, a bike with cases is more desirable, so you might not be able to persuade such a seller.
Just after I saw this thread the other day a set popped up on the facebook group for sale cheeeeeap, and were summarily snapped up by some lucky dude. I would have given a link, but they were marked sold by the time I saw them.
But, yeah, maybe join the facebook group (fj-09 owners association) and the tracer900.net forum and poke around. As was mentioned, someone might be willing to trade. You could remove and keep your own locksets and just swap boxes.
I tried to find the cases on the microfiche at Partzilla but was unsuccessful.
