The current carrier already has it and it's still a shot magnet from the side. It's simply too big and turns too slowly. Plus, the crosshair can be moved upper into the "shell" section if anyone thinks the shape will have any influence.
PS: Additionally, the carrier can only fire half of its armament to the side, so if you really want to trade half of your firepower for being a bit harder to hit (if you were, that is), do it.
