I used almost your exact team and gear levels (of course scout and tebo stay on the bench). Basically its alot of rng, but focus on giving ewok elder all the assists/bonus turns
It's a grind, but w the toons you have it should be possible

I did it with one or two bears g10, the rest g11, zeta on wicket and chirpa. With some patience, yours should be more than enough.

You are probably good.
I had heal bear at 12 and the rest at gear 11.

I go with a Chirpa lead and my speeds range from 169 on Paploo to 222 on Wicket.
I get devastated before I even get a chance to strike ?

Gear level seems ok but speed is a bit low.

Farm Wicket and more speedy mods. Don't be afraid of gearing them, they are a good counter to FO in GAC.

Around this level will suffice

Your Ewoks are strong enough. They probably need more speed though. The key here is that under Chirpa lead, all of their basics generate 20% TM. And Elder is even more key because his basic generates additional TM for himself and his allies.
So make Elder as fast as you can, and prioritize him as the target of all your assist calls. Logray has high base speed and has a TM generating move for his whole team so he should be the fastest. Paploo gets a significant 25% speed bonus when he's not taunting which is important because he also calls an assist, so it pays to make him speedy too. Wicket is your damage weapon so mod for offense and speed. Chirpa gets whatever speed you have left.
I did it with the first five of these guys. There is hope.

This is what I've done.

I've farmed Health Mods. Every Ewok gets a +30 speed Arrow, and a +10 or higher speed secondary mod in every single slot. It's not hard to farm, and easy to acquire. You are more than geared. Just fix your mods.

When doing the battle, always cloak Elder with Wicket's Special. If Elder dies, redo the event. Keep Elder cloaked as much as possible. Use Elder Revive when an Ewok dies, keep the buffs up, clear any debuffs.

Kill order matters, make sure you remove taunt from the resistance tank, focus fire Chewie, then Hans, Tank, Leia, and the final 2 droids.

It's all based on RNG too, so it will take a few refresh before you get the perfect run.

You’ll never do it without a R5 Rose Tico.
