What about this list:
Laetin A'Shera w/ Heavy Scyk and HLC
4 x Cartel Pilot w/ Heavy Scyk and Ion Cannon
The idea is that you can fire away at any range and Ionize many opponents. Laetin is there to hit things and add the punch because Ions alone won't do it. The way I see it is that if there is a big ship, these things will be able to Ionize it every turn. Laetin can clear any C-3PO and other evades. The Ions just pummel it. You can Ion something off the board. Stay at Range 3 and your high green dice should help. The Ions still do a point of damage every time. If you can stop ships like Fat Han or Dash from doing any maneuvers, you can do well against them.
What about a Swarm? Well, at Range 3, you can Ionize half of them and get the extra Range 3 evade vs. all the shots. Your mobility should help you get around them and break up their formation. Then they aren't half as bad.
Phantom? Well, if you can get a solid turn of shots in to Ionize one, I think you'll do it. Four Ion cannons firing will most likely tag it once. Once Ionized, you just need to keep firing. It will be pretty predictable going 1 straight. It only has 4 hits before dead.
3-4 ship list (like 4 B-wings)? Oh, that would be a joy! You have a decent chance of ionizing each ship every round! How hysterical would that be? If they have no turrets, you can just walk them off the board.
You could go with Serissu w/ Ion Cannon and Stealth Device. That would help Serissu from being blasted on the first turn and help anyone near her. The extra Ion Cannon will mean less damage, but more control. You can pretty much guarantee that you will control a lot of the enemy.
Thoughts?
