I have been working with Rey and two Sheathipede shuttles and have come up with the following list. It allows you to Deny focus/TL actions with Fenn, strip stress off of Rey and give her actions pre &/or post move including combos like:

Expert Handling BR remove TL, perform a green remove stress, perform evade, Fenn coordinates a focus to Rey.

AP5 remove stress from 3k Rey just did, Rey gets action, 3 or 4ks again for position.

This build puts a lot of damage dealing load on Rey but enhances her defense quite well.

I am playing with an ezra variant as well, where AP5 uses Chopper(crew)/Pulse Rey Shield to keep giving Rey actions instead of shedding stress. Ezra relies on R3-A2/tactician combo to hand out stress. Rey has kept expertise/countermeasures and a rigged cargo chute in this build.
