I'm thinking the following might be a solid counter as it'll you should be able to survive fire from the resulting 2 scouts:
GRAY SQUADRON
99 points
PILOTS
Gray Squadron Pilot (33) x 3
Y-Wing (20), R2 Astromech (1), Plasma Torpedoes (3), Proton Torpedoes (4), Ion Cannon Turret (5), Guidance Chips (0)
I cannot help but feel that is a bit over-equipped. R2 astromechs are handy if you have the points spare but don't add a huge amount to this list. Plasma + Protorps on one ship costs 7 points. Take one or the other and put extra munitions on (redundancy is nice but points are better).
Ion Cannon turrets are a bit pricey and only really come into play once your ordnance is spent. If you drop the turrets, R2s and go for extra Ordnance, you can save 22 points which is enough for a decently equipped Green Arrow to either block or get around the back of enemy ships.
