Since the list consists of all durable ships, I would suggest another durable ship. If you add in or substitute a glass cannon, it's pretty pointless since it'll just get killed first anyway.
Tarn + R7 is perfect. Super-tanky with his ability + R7, especially in the end game. Try and fly / position him in such a way as to keep him alive until the end.
Tarn + R7 (25)
5x Prototype Pilot + Refit (75)
Bonus: you at least have 1 ship with 3 dice, so he at least will have an easier time dealing with 4 defense Phantoms.
In my experience, I've never known A-wings to be all that durable. If they can be shot (and of course, the trick is make sure they're not shot), they go down very quickly. I just don't see this list working as intended.
I'd be licking my lips, flying my swarms/mini-swarms, playing against this.
