I've done this...its just not as good as drops with hoods. The hoods give you a very good climbing hand position (essentially like bullhorns) and you also have better access to your lever from multiple hand positions.

YOu may think its more visually appealing, but to me it looks like a silly noob setup. I'm curious, what do you mean you like a cross lever setup more "flow wise". Because hoods have much better "flow" to them, unless you think sitting upright and changing hand position everytime you feel like you might need to grab your brake has more "flow". Cross levers are a big PIA when you start going fast (especially when going downhill), because you can't keep you hands down in the drops, unless you are riding somewhere there are no intersections or traffic.
