Just stumbled on this video: . I had this thought earlier too, the only game I can think of that allowed you to do something like this is Diablo 2 and the Crusader in Diablo 3.
I think that it'd be a pretty cool thing, something inbetween both the damage of Two-Handed fighting and the defense of One-Handed and shield. Very unique too as far as games goes, something you VERY rarely see. It actually makes some semblance of sense too contextually in the setting if people want to argue that when you take into consideration the things that people fight. If you fight a monster and lots of missile fire etc.
