Definately. Lower the dex requirement for x-bows, but increase the ap cost to use it, or maybe have a seperate load action for it with a hi ap cost. But never should more than one shot per round be possible. I also would like to use crossbows in the manner you describe, you dont have to be freaking Legolas or robin hood to use a crossbow, they are heavy and unwieldy and godawful slow to reload....dex requirement of like 5 or 6.
