CM Punk may not be the last WWE star to get his shot in the UFC ... 'cause Octagon star Alan Jouban is saying he wants his crack at a wrestling legend ... 7'0", 440-pound Big Show.
Jouban is 6'0" tall and fights at 170.
We got the (very brave) UFC fighter out in L.A. and asked him if there was any WWE star he'd like a shot at ... since Mickey Gall made such short work of Punk.
Check out the clip -- Jouban calls out Big Show ... saying he thinks he could use a stick and move tactic to outmaneuver BS and get a W.
Big Show outweighs Jouban by 270 pounds, that's more than The Rock weighs ... don't do it, Dana.
