I came up with this crazy idea while discussing the impact of interiors on ship performance. The main problem I see is that there is extra weight that only adds armor and hull HP, and nothing else of any use. This leads to ships with interiors being forced into an armor tank meta, where they tend to be slower and have less firepower than undecorated ships of the same mass.
More empty space inside = more surface area = more armor mass = slower or more thrusters.
More thrusters = less shield or less firepower.
This could easily be solved by adding a fourth type of armor that provides shield capacity instead of armor HP. Yes, I know it sounds silly, but instead of thinking of it as "armor that adds shields," think of it as a pretty shield capacitor that you can use for decoration in or outside of your ship.
Now, there is still the issue of decoration blocks adding extraneous weight, and nothing useful aside from hull HP. This could be most easily solved by making the blocks almost weightless. How light? How much does a computer weigh compared to a solid piece of metal the same volume? Not much. For game mechanics, I'd say make the decoration blocks weight about 1/100 as much as hull, and provide a proportional amount of HP. That's trivial enough not to matter even if you use a great many of them as I like to.
