Too bad the game prog can't allow using something like the "pimpship" to upgrade other things with the ships.
I'd pay a substantial amount to be able to upgrade a shield/powerplant/weapon hardpoint on a ship by say one step. Like being able to upgrade a large freighters class 7 shield to a GB class 8 shield, I'd pay 40-60+ mil cr to do that with a powerplant to match. I'd pay 20-30 mil each to upgrade a class 7 freighter mount to a class 8 GB mount.
I wouldn't mind giving up some cargo space to do this.
