Fraid it is just not possible

ok, thz, it was hust to know.
becaus a gun like that would boost the cooperative play on the mods.

Maybe by creating specialist versions of ships. You could have a ship which could have higher than normal nano and shield gen capacity, but, reduced armour and maximum weapons.
They would need to have an escort in order to travel around the more difficult regions of the sector. I think freighters would be the best choice as they are not geared for combat and players wouldn't just buy the support ship and use it anyway.
