I'd imagine that a drone with the capabilities of the A10 would end up looking a lot like the A10, without the cockpit. The size of the airframe is pretty much dictated by the size of the GAU8, which in turn is dictated by the size of a 25 mm round. The flat wings are there for slow-speed flying. The gun is mounted inline with the centerline of the aircraft (or, more accurately, the firing barrel is). It is built for a purpose, and does it well.
