Well since his style and moves seem to be customizable through conquest mode, I'd say you'll probably be able to unlock a few of your own to choose from.

I'm not saying that I know much about konquest, because I don't, but are we sure hat you can actually custimoze this guy. From how things sound, I thin that you may just go through this whole konquest to learn a premade set of styles, moves, and fatalities. Otherwise, it would be weird to make him a playable character in the game.

he will most likely learn fatalities from people he meets along his journey, so he may learn johnny cage decapataion, or kano's heart rip. you never now until we play it
