So please say what you think of the following list?

Scum Everywhere (97)

Karthakk Pirate (32) - Scurrg H-6 Bomber
Synced Turret (4), Adv. Homing Missiles (3), Boba Fett (1), Long-Range Scanners (0)

Thweek (27) - StarViper
StarViper Mk.II (-3), Autothrusters (2)

Cartel Brute (26) - M12-L Kimogila Fighter
Harpoon Missiles (4), Long-Range Scanners (0)

Sunny Bounder (12) - M3-A "Scyk" Interceptor
"Light Scyk" Interceptor (-2)

It's has harpoons for a bit more damage, Boba to remove key upgrades easily with Adv homing missles such as tlt or dashes hlc, Thweek can either move last or if there's a ability such as fenns it could be key and finally sunny is another ship that can just peck a little bit per turn?

What would you change to improve?

It's got good bones. I really like four-ship lists, especially in the current meta, and especially when they don't want to be in formation. I would tinker a little with your Pirate's load-out - Swap Synched Turret for AutoBlaster Turret, Lose Adv. Homers for Proton Torps. I'm too lazy to use Adv. Homing, although I see what you're going for. And I get how it sort of synergizes with Synched Turret, but LRS makes that so difficult to exploit. Protons make it potentially easier to trigger Fett, while packing more punch, and ABT is just gravy on a ship that barrel roll.
