As a mad scientist I want the artificer in the game, even if it would probably not be my first char. I would probably play them as gnome, they are known for being nuts, think of Jan Jansen.
Since Larian makes the game, a robo pet or summoned cannons would probably not be the craziest stuff in the game.
