Palhares vs Lister (no gi)-this would probably end in a draw due to four broken legs.
As much as I would love to see a Royler vs. Eddie 2 rematch to put up the money to get Royler alone to compete would be way more than any of the other fighters would be making. Metamoris is still in it's infancy as an organization, if they shell out to much money, to fast this could very quickly look like an Affliction like situation. I think he asked for around $50,000 to show for an Abu Dhabi Superfight. If the Sheikh, who has more money than God couldn't put up the purse for the fight, the Gracie's probably would have a hard time getting him to compete. Still if someone could ever make it happen, I am sure everyone and fans around the world would absolutely love it. Eddie would promote the shit out of it too
I would honestly have picked Frank Mir over Brandon Schaub or someone known for have really good technical Jiu Jitsu, I think Frank Mir is to large for Cyborg but still I wouldn't mind seeing him compete in Jiu Jitsu. Marcelo vs. Rafa Mendez would be another dream match. Keenan vs. DJ Jackson would be good since DJ and his boring grind-fuck style feel they can some how submit Keenan.
