I was just thinking about the effect of having Epsilon Leader and Yorr flying in formation. A third ship would be able to remove four stress every round.

One stress token will be removed from performing a green maneuver.

Two stress will be transferred to Yorr as they are assigned.

One stress will be removed by Epsilon Leader's ability at the start of combat.

Epsilon Leader will allow Yorr to remove two stress every round. One from his green maneuver and the other at the start of combat.

Is there any useful way to make use of this interaction that isn't just a straight up gimmick?

Gimmicky, but another shuttle with Advanced Sensors, Experimental Interface, and Fleet Officer could trigger Advanced Sensors, take an action, use EI to trigger Fleet Officer (both stress tokens are taken by Yorr) and then perform a stop maneuver. Yorr pulling a green and bumping and Epsilon Leader's ability will clear the rest of the stress.

I don't think Yorr will get much use out of Advanced Sensors. The lower PS Shuttles will be tossing him stress before he activates. Maybe give him Rebel Captive so your opponent can feel some of the stress?

I'm more interested in filling out some other ships that can benefit from Yorr and Epsilon Leader stress removal shenanigans than I am putting together a complete list.
