I feel like making him full Kryptonian would be a cop out and also fly in the face of their own established logic. Match is full Kryptonian, and because of that he has mental instability. The patches suppress Conner's human genes, and because of that he has fits of rage like Match because that's the price of cloning a full Kryptonian.
I'm honestly getting more and more attached to the "Cyborg Superboy". It acts as a direct homage to Reign by mixing Conner and Henshaw right after Conner has gone public as a hero. And if they get a next season, Conner being "Cyborg Superboy" full-time after Clark has likely stepped back a bit more to raise Jon with Lois you'd have a consolidated version of Reign-- especially if they have him and Steel act as a team to equal up to the hole Clark will leave behind.
Looks wise, I'm envisioning something that's not all super Terminator. Like skin grafts for a burn victim...but future metal.
