I doubt there'd be one-handed crossbows in Dawnguard. If you're trying to compare to a more "medieval-style" crossbow, it would have to be two-handed. Though, the damage output would likely be a decent bit higher than that of the bow, but end up with a slower 'reload speed'. IRL, an archer firing a bow can fire as little as three arrows compared to a crossbow combatant firing one bolt, which is what they will also want to add besides sticking with just arrows.
