Sooooooooo......

Trando-something hunter-29

any IG-88-36

Madolorian thigny--35

The scum triple large ships. Boom.

not really great at hunting bro-bots, though

bro-bots have some ridiculous efficiency between HLCs, thrusters, sensors, and EPT. Their weakness is their large base + arc (hate obstructions), which is something the above list shares with them.

The generic YV will be easily outmaneuvered or rendered useless between its poor dial (again, obstructions) and the fact that naked dice really suck against long range Aggressors

If you want to hunt brobits with YVs, you're going to want stress (brobots suck when stressed) ala tacticians or just dump the bossk + gunner combo to brute force your way through greens + evade. The PS 5 reducing agility could also be incredibly brutal for them to face.

You'd probably want to run IG-88C or D.

It might be good...

Definitely sounds fun. I get the impression it won't be quite as good as the the Imperial "Big Guns" list, though (Bounty Hunter, Doomshuttle, Patrol Leader; 3 points for RecSpec or Rebel Captive).
