*nods to Agent Z, for his Bone vs Boyka thread, that inspired me to open this one*

Basically, you have this gangster, Gambol, played by Michael Jai White, who is one of the major players at the start of the Dark Knight, before the Joker starts doing his thing. However, he was missing something, namely White's martial arts skills. As such, the Plot Gods give him another chance, by giving him the composite abilities of MJW's various human characters (so, no Spawn or any other explicitly superhuman character he ever played). How much this gift would change the plot of the Dark Knight?
