I was thinking about list ideas where half the list would charge right in and engage while some TLT Y-Wings would keep their distance and pound away. The screening units would need to be tough (since they'd be charging directly in and drawing attention) but also need to have enough firepower that ignoring them would hurt. Brawlers, basically, but with a defensive bent.
Scum Y-Wings would be preferable since they can have more consistent damage with the R4 Agromech, but Rebel can work, too. The simplest version would be 4 Zs as the screen (YYZZZZ):
Syndicate Thug + Twin Laser Turret + R4 Agromech (26)
Binayre Pirate (12)
Binayre Pirate (12)
Binayre Pirate (12)
Syndicate Thug + Twin Laser Turret + R4 Agromech (26)
Syndicate Thug + Twin Laser Turret + R4 Agromech (26)
