on the power and crew meters, if you scroll over the max and min suggestion bars (the red and green lines) additional bars pop up, sort of like this.
[What they are are a breakdown of power or crew required by certain systems
organized in order of power usage.
So what this pic means is, the minimum crew suggested for weapons on the ship is the least, the engines use that much more, then the shields and PD, then the the minimal crew suggestion for "other" systems uses the most.
So this ship probably has 2 guns and is about 50 sensors, which is silly but just a theoretical example. If you scrolled over the default green maximum suggested crew bar the lines shift appropriately.
I think it would be easy because the system is already there, you would just need to tag each part with a "type" for its own pair of sub bars on the meter. To further illustrate, if I stripped a ship down to just weapons, crew, power, and ammo production, I would then have the min and max suggested values for the red "weapons" line above shown on the existing power and crew bars.
