If I was Calgary I'd trade for Duclair. Whether that's shipping over Dillon Dube as a way to restart his career, or just use some late round draft capital (5,6-7th rounder).
Then I'd run Zary down the middle with Huberdeau and Duclair. It's about as close as this franchise can get to having a Panthers type line. Give them easy matchups, and make sure that Weegs, Tanev, Razzy or Noah are on the ice when the line is out there and not the third pairing.
Duclair is UFA after this season making 3M. Best case they find chemistry and you make it happen on a 2-3 year deal with him, worst case it doesn't work out and he can find a new home in the summer.
