I believe Hedge commented on this very thing in the context of chaos wastes. I can't be bothered to find the source, but we might be getting just this soon.
Edit: Because this seems to have had some traction, I did some digging and found the mention in question, where Hedge talked about using the illusions from WoM to help bridge the Athanor system into Adventure Mode. It's the first comment in this thread.

Edit II, Athanor Boogaloo: I was wrong with it being linked to chaos wastes, but it's still something being considered, just lacking an ETA because of complications with Athanor implementation which would go hand in hand with the weave skins.
