Possibly, but you'll probably need to replace the radar on top with an optical targeting system, and if you're really smart have cheap optical targeting pods that are separate from the gun. Drones can come in low enough to be all but invisible until it's too late. You don't want them trading 10 drones for one cwis over and over, so spreading out the sensors will make the attack on the gun less debilitating and allow the gun to see them coming before they can fire on it.
