Sounds like you may be looking for a Cyclo-cross (for example the Surley Cross Check) or touring bike (Bianchi Volpe, Surley Long Haul Trucker, Windsor Tourist, etc, etc.).
You could get a hybrid and change out the bars. However, you might also have to change out the brake levers and the shifters, since hybrid bars and road bars are usually different diameters.
You also need to watch out for the fact that many hybrid bicycles have low-end components. Usually not what you want for commuting, although it would work for a while in a pinch.
