I posted this elsewhere when someone else asked, it's exactly what I used. Only difference is I have them level 85 across the board. That won't affect abilities unless you intend to zeta them. And only minimal change to health and strength.
Hera G8+4, 170- 6 health mods, protection on triangle and circle. Tenacity on cross. Speed on arrow.
Chopper G8+4, 209- 6 health mods, protection on triangle, circle, and arrow (15 speed secondary), tenacity on cross.
Zeb G8+3, 132- 2 health 4 potency, protection on circle and triangle, potency on cross. Speed on arrow (actually forgot to put the 5-dot one from my arena FOST. He only had a 1-dot speed arrow). Potency 65%.
Kanan G8+3, 111 - 4 health, 2 Crit chance. Protection on triangle, circle and arrow (13 speed secondary), tenacity on cross.
Ezra G9+4, 173 - 4 offence, 2 health. Health on circle. Crit damage on triangle. Tenacity on cross. Speed on arrow.
Pretty straightforward if you avoid Thrawn until the end, unless he has daze/stun. DT's first, ST's, then Papa Smurf. The tenacity helped a ton as they were rarely debuffed except for the unavoidable Fracture.
First try, all with health/protection by the end. Kanan and Zeb utilized backup plan off of fracture, that was it.
It maxed out protection as much as I could without sacrificing too much speed and I ended up with all 5 alive with health and protection at the end.
