With PS6 interceptors, and no named ships on both parts, you will have troubles getting anything that they can't arc dodge. Turrets are the most obvious solution, and can completely shoot down Push the limit interceptors, since ion + stress = bad.
I would use
Gold Squadron Pilot (18)Ion Cannon Turret (5)R3-A2 (2)Gold Squadron Pilot (18)Ion Cannon Turret (5)Flechette Torpedoes (2)Total: 50
That's your perfect counter squad.
2 Golds + Ions at 46 points should be just fine too. The final 4 points of upgrades are just gravy.
