I've also considered it. From what I've read, they use our dreamotion energy to forge a connection to our world, so it must be related. However, I'm not sure if the items maintain that connection or if they change upon entering the world—which would be important to look into. The biggest question will be as always, "how," but there must be a way to detect it. I'm thinking of going to the Observatory to see if they have anything that might work.
