I am going to try:

Rear Admiral Chiraneau

expose

gunner

mercenary copilot

Patrol Leader:

Darth Vader

If you dropped the Mercenary Copilot you could put APLs on the Patrol Leader or switch him out for Oicunn. That would give the chance to deal some damage during the Activation Phase.

Without experimental interface, I don't think expose is worth it. You might run some numbers on EI (target lock plus cheery's soft focus) vs. Gunner.

dropped exposed for marksmanship, Between Chiraneau's ability, mercenary copilot and marksmanship and vader I should be dealing at least 1 critical every round.

Marksmanship is a waste when you already get one focus turned to a crit for free (but only range 1-2). You would have to get at least two focus to make marksmanship work. You're better off taking a target lock.

I would drop gunner to add experimental interface. Use the two extra points to put APL on the patrol leader.

I don't own Experimental interface. I don't buy rebel ships

I don't own Experimental interface. I don't buy rebel ships

That's a shame. You're passing up a lot of solid upgrades.
