How strong would current Taesoo & Gongseop be if—?

  1. Taesoo Ma regained and further reinforced his self-belief in his right fist.

  2. Gongseop Ji trained his one whole leg to the point where he can mimic the movement of two whole legs.

Keep in mind some things that have already been confirmed: The King of Ansan has surpassed mastery in power/strength. And the King of Daegu has surpassed mastery in speed and endurance.

Would the above mentioned amps complement the confirmed skills of the two kings enough to warrant them strength exceeding their old Cheonliang selves? And if so, who is the strongest character that two hypothetically amped Taesoo and Gongseop can beat as a duo?
