There is going to be a stage during this where Kon reverts to a time he was completely mindborked and extremely violent, and only obedient to Lex Luthor.

So, uh, there could be a brief stage of an out of control superhuman if we want one. Thing is, he is incredibly powerful, when you get down to it. Even beyond the flying brick powerset, he's got the tactile telekinesis. He totally like leveled the entire Teen Titans when he first turned in the comics.

So this would be difficult to handle (but also potentially interesting).
