Do it like a strange flying wing. Standard titan/praet/gladi model, more or less, but with cockpit on one end of the wing, and SNAC/CD mount on the other end, with guns evenly distributed all over the ship. That way, you might even get away with that much guns. Tho, don't make them all class 10, too much codiepower there... just make them all class 9 or something like that.
