Hmm, I thought about something like that before, but now I'm against it because
1. It doesn't make too much sense from a steampunk perspective. Already the indicators are a little heavy on the UI side (but obviously necessary or else engineering would be a nightmare), but a full ship HUD overview seems like something that would fit in a sci fi game (like EVE or Star Citizen, etc) and not in a steampunk kind of lowtech setting.
2. It would make engineering too easy - a key part of high level engineering is noticing damage and prioritizing repairs/rebuilds/shooting/spraying.
3. I've gotten used to the icons and when I don't notice them, I blame myself if I fail to notice it and the hull goes down and strive to become a better (more aware, at least) engineer while shooting, etc.
