A couple of suggestions...
Sector Cloaking Device. The Ability Sector - Sight Obscuration works on planets and components, it cloaks planets too. I think that every Sector wide ability in the Abilities.txt file works on components, not sure of this though. Especially Sector - Damage might me interesting on a ship
.
From system wide abilities atleast Planet Value Change - System works on components. Possibly the others work too.. i havent tested them yet.
Components based on these might be nice to see in mods.. though i could imagine that they would cause serious balance problems if not handled correctly...
btw, that point-defense repulsor component idea rocks...
