Venture Co. Mercenary transmog

[Plaster]

For those of you who don't play Hearthstone, there is a big bruiser of a card called the Venture Co. Mercenary, and he looks amazing. Most Hearthstone art has characters in playable gear, but so far I haven't found anything even resembling this guy's gear. Does anyone know where this comes from? Or does anyone have a set that resembles this gear?

this looks a bit the same

or have a look through here, I selected rogue look because he looked like a rogue more than a hunter

There's nothing really like that in the game.
