I do think the trophy aspect may be important to some, like the Vision of Skullcracker, Lillu introduced as "New unique illusion clicky is available from one of the ldon adventure merchants (treasure). Please note, this item is intentionally expensive, meant to be rare and precious!"
Not sure if that can be done with an aug. Maybe like some donor items one could get a separate clicky for the illusion. I'm sure that some folks, like muscle builders in a gym, would enjoy "flexing" their million HoH points to burn by turning into some unique illusion.
