Two tries after I settled on this lineup:
Chirpa (L): 7* g8
EE: 7* g8
Paploo: 7* g7
Teebo: 7* g7
Wicket: 6* g7
It was pretty dicey at times, I had to revive a lot and everyone was down pretty low more than once. My mods were nothing special, but all lvl 15. The posts above are pretty old, but still relevant—ignore the troopers on the waves you can damage the walker, give turn meter to EE when you can, use paploo's basic to dispell buffs, and be prepared to revive often.
FWIW, I tried 3-4 times with Logray and Scout instead of Teebo and Wicket because my Wicket is only 6* and Logray is 7* g8, but the lineup above worked better for me. Wicket's assist is awesome and I assume Teebo was doing some turn meter wizardry I didn't bother to keep up with.
Edit: I should mention all my ewoks are level 85. I'm guessing level 80 was the cap when this was originally posted.
