Re: Base gun damage on calibre and gun size; armor divisor on kinetic energy?
Great; a problem has been identified. How do we fix it?

GURPS' hit points are a good reflection of how hard it is to reach the vitals of a target, but not a good reflection of how hard it is to carve them up one small piece at a time. This is why they give decent results when dealing with attacks of the right 'size' for the target they're attacking (e.g. tank gun vs tank), but allow rifles to shoot up ships of the line far too easily.

Re: Base gun damage on calibre and gun size; armor divisor on kinetic energy?
Honestly not sure how to fix it within the system you proposed. You simply must account for the fact that penetration depth, and therefore velocity, is more than a minor factor.

Re: Base gun damage on calibre and gun size; armor divisor on kinetic energy?
Using rules as written does an okay job at that.

I think to create something just as simple as and more realistic than Doug's model, you would need domain expertise in those subjects I discussed. Interior ballistics ("wounding") is a subject where lots of highly educated or experienced people scream at each other without coming to a consensus, beyond that a human being is likely to be in worse shape after being shot by a .50 BMG at 100 metres than a 5.56 mm NATO, and in worse shape if hit with the 5.56 mm NATO than a .32 ACP. I don't have that domain expertise. I am not saying that its obvious that those ~ 8mm ish military rifle rounds from before 1914 do three times as much wounding as a 9 x 19 mm Parabellum, just that GURPS gives broadly reasonable results when humans and human-like characters get shot.

Handling for getting hit with a cannon may be iffy and the way multiple hits accumulate is often criticized.

Replacing HP ablation with tracking individual wounds is probably worth putting to the side since its separate from modelling individual wounds. The "light machine gun quickly destroying a large wooden ship by HP ablation" problem is related.
