At first, the idea of having the sound of bullets shattering and pinging across your hull would be neat, it would probably get annoying fast due to the amount of Gatling fire that most ships experience.
However, you should have no problem noticing your hull being damaged, because any engi worth his wrench notices when something is damaged, and any engi worth their Moonshine always keeps an eye on the hull health bar. So noticing damage shouldn't be an issue.
