If I were to do this, I would overhaul some of the warship construction rules/options. First would be the inclusion of intro/low-tech versions of most of the weapons, then add advanced/high-tech versions of the weapons (nlasers/nppcs might get a small damage boost overall, while ngauss might get better mass/damage ratios, and nacs maybe a slight range increase and more shell types, missiles would get different types, such as bomb-pumped lasers, EWAR, micro-munitions, etc.). Fire control could be increased from 20 weapons to 25 per arc (or maybe only 22, but a bit of an increase none-the-less), potentially separate fire control systems for capital and non-capital scale weapons. And more versions of armors to add additional versatility to protection factors.
