Of course. The more I see people discussing it, the more I'd wager that fusing two Legendary single-element armors will create the respective Ultra Rare dual-element armor the majority of the time (80% of the time? 90% of the time?).

Chitnuous was 1 and Cloud King's was 11. And yes, both of them are armors that are crafted from the materials dropped by weekly bosses.
