REY and REX
It's a cool idea, as it splits their target priority, and makes Rey even more dangerous.
However, I'm not sure if you're using Rey to her fullest potential. She'd do better with Kanaan instead if the copilot, APL generally isn't good on her, and wired, while good, is going to be hard to trigger; you would do better with veteran instincts.
As for the rest of the list, you might want to consider switching the two Z-95s for Ezra in the Phantom. Toss Rage, Hera, and TLT on him, and bam, you've got a dodgy bastard who can also hit relatively hard when he needs to.
If you're trying to go with the ships you already have, you're going to need to buy the two Z-95s anyways; you may as well spend the extra ~$20 on the Ghost expansion, as the crew and ships in that pack have become a staple and almost must-have for rebels lists.
The APL, I'm not that sure of.
I was first going to suggest Biggs instead of the two Z's, but that would require a lot more formation flying and that is something you'd not necessarily would want to do with Rey.
my idea behind this was rey would be off in her own little world drawing out the opponents ships where rex is leading a squad of him and 2 z 95s to flank. or vice versa.
