This is a fine ship, for what it is, but you can add effects which multiply shield damage to get more shield damage with the same amount of blocks. If Ion isn't your thing and you just want maximum damage, then use the piercing effect. The Ion effect increases damage to shields but decreases damage to the ship The piercing effect increases both damage and blast radius.
Also, there is no real reason to have a docked superweapon within a ship. You cant aim it and fly at the same time. You could say that a bobby AI would be used for aiming/firing, but with a ship big enough to use something this big you wouldn't be able to turn fast enough.
Logic superweapons are useful for firing multiple weapons at once, or increasing rate of fire. I can tell you more about this if you are interested.
In summation, put in an effect for more power, and copy paste it into a ship because docked weapons that arent turrets arent useful.
