Simple list:

Howlrunner (40)

Sienar Specialist, Ion Cannon Turret, Veteran Turret Gunner (40) x4

Total: 200

Howlrunner gives your primary attacks a reroll, and you'll have focus (and/or TL if you can get one) for the turret second tap. Being able to rotate means you can cover flanking aces and you should still be able to get double shots off.

5x two dice with reroll attacks plus 4x 3 dice ion attacks.

Viable?

Sweet why not? You have the option of making Howlie survive longer with giving all your Aggressors Dorsal over Ion if you find her dying off to quickly. Could get elusive hull or shields

otherwise I like the set up

I run a similar list with Scum Y-Wings:

Drea Renthal: Predator, Dorsal Turret, Shield Upgrade, Veteran Turret Gunner (56)

Hired Gun x2: Predator, Ion Cannon Turret, Shield Upgrade, Veteran Turret Gunner (49)

Hired Gun: Predator, Dorsal Turret, Shield Upgrade, Veteran Turret Gunner (43)

Total: 197

Your Aggressor List is IMHO just as equal to my Y-Wing list. The Scum list advantage is having more Hit points and Shields to fight thru per ship than the Aggressors, and getting Predator on them allows for Two Dice Re-rolls in the right conditions. The Empire list advantage is fielding a Fifth ship, and those ships have better Defense Dice rolls and Maneuver templates.

I would love to see you field this, and hear your notes on how it plays.

I'd be tempted to include Iden just to help Howlie in the initial pass, after which the Ion moves should keep her pretty safe

How about this?
