Actually, even though this is cool, through my testing it seems that you can't have a hybrid due to the fact that he is a simbot. You see, what makes a simbot is hidden clothes and a trait, so if you take off the robot clothes and put on normal ones, even if he had looked like a normal sim, the game still thinks he's a simbot thus making it impossible for him to turn into anything else. Because through my testing, I've found out that he looks normal but is actually a simbot.
