I did switch mods on Rey and Chewie for tier 5, and got it after 5 attempts.
Was actually easy, compared to Thrawn.

I managed with this:


Rey: G8, L85
Finn: G8, L85
BB8: G10, L85
Han: G8, L80
Chewie: G8, L80

Rey, Chewie, and Han got arena mods since they didn't have any to begin with. BB8 already had pretty good mods so I kept him as is, and Finn did ok with the mods I already had on him until P5 where I put Poe's on him just for some extra speed. That did the trick. It still took me about 10 tries on P5 to get it.

I did have Finn's zeta, which I didn't think would make a difference, but it actually helped out in Phase 5 to give some added TM to Rey and Finn.

Finn: speed and protection(because yours are G8)
Rey: CritDm+CritCh
Chewie: Offense — For a lot of Dm

These are the point how to mod them.
Of course secondary stats must have high speed.
