I think that would be a bad night for Cejudo. Volkanovski is not tall, but he sure as hell has big frame and lenght for his size. And on top of that, he is better striker than Cejudo. But Henry sure can try.
Also, dude is highly overestimating himself. His two best wins are debatable split-decision and ko of half dead guy who fought for his life to make the scale. When you remove that, you have a win against Dominick Cruz, a fight in which judge took Dominick's right to compete in a dirty manner. Even funnier, same judge allowed Marlon Moraes to lay flat on the back with arms limp while not defending himself for more than a few seconds, not counting 300 other punches he got clean on the head without defending. I mean, Merab was hurt more than Cruz, let alone Marlon. All in all, for a guy whose best wins are those, who's got like 2 title defences, he sure talks a lot about himself. He is not even close to what he portrays himself. You need consistency on top and some kind of domination to enter those conversations. he just started a path to it.
