With the new nerf to Zuckuss is it possible to make a party bus using him and two inspiring recruits to help manage stress or can you only have one recruit on there?

Since Inspiring Recruit isn't limited, it is possible to have Zuckuss and two of them on the bus, allowing you to remove 3 stress from each green maneuver. However, I'd probably do Zuckuss, Inspiring Recruit, K-4 Security Droid instead, so that you can still Zuckuss twice, and then you also get that TL for your own dice.

Dengar instead of K4; so you don't have to pick a target.

Expertise instead of either Dengar or K4. Zuckuss triggers on the defense roll, which is after the attack roll. Having an Inspiring recruit onboard along with another crew member (maybe even Dengar) on a Bossk party bus means you get a focus modded shot, then get stressed, then lose it by pulling a green maneuver next round.

I wouldn't spend 4 points to put Expertise on any ship with a high probability of stress. Between the dial and Zuckuss, this bus will be highly vulnerable to stress control. In other words; good chance you won't get to use Expertise. You could go for Predator to get rerolls, then open your third crew slot for something else.

A ship with Inspiring Recruit has a pretty god chance of using expertise. Predator is a safe choice, but I think Expertise has potential if one's list as a more distracting element in it like Fenn Rau to draw the fire.
