Interesting story, I'm not really sure how I'd advise you do it, but with enough discipline you can, of course, balance the rationality of your "good" half and the aggressiveness of your "evil" half. That's what Kirk always did, anyway. Otherwise he'd have been spending all of his time stumbling around the ship in heavy eyeliner and a cold sweat, swilling brandy and boffing his yeoman.

The transporter would be handy for all sorts of reasons, especially if it could filter out whatever was wrong in our heads and reconstitute us as something "better". I'd take that trip. Then again, they tried putting those two Good and Evil horned space poodles through the transporter and look what happened to them. Still, those were only dogs. As for you, "you have your intellect! You can fight with that!"
