You've got a lot of high cost ships there, as well as Combat Retrofit. Generally the GR-75 prefers Automated Protocols, and you generally want cheaper ships that either have decent agility, or are better on defense.

If you want Ion, naked Ys with Ion Turrets, or Bandits with Ion Pulse and Chips generally work decently well, especially if you toss Shara, Esege, or Kyle behind them as a support ship.
