I would love to see some upgrades like that. Here are some (though some might fall under "upgrades"):
- Armor Upgrades. (I get the feeling that "force field shields" are not part of the Wormhole technology universe. - Thruster boosts - Emergecy Power relays (maybe to prevent Power Loss from affecting orders?) - Charge Magnifier (for Particlebow), maybe making a charged cannon more powerful (as if it wasn't nasty enough already).
And of course, additional weapons that you could "add" to the ships would be cool.
