My group stumbled upon the upgrade rules in the EotE core book, the other day, and has been wondering what the limits are on upgrades to ships...specifically, to the ships weapons.
The group has been wondering if it is possible to upgrade a weapon system on a ship from a fixed firing arc to a 360 degree turret. Their ship (a Wayfarer-class) has a dorsal weapon mount that only fires forward. Is it possible to upgrade that to a turret, and if possible, what would they be looking at for hardpoints, cost, skill checks, etc?
