Darth Revan without zeta on Carth ?

i did it with g8 carth, canderous, juhani, g11 hk and g10 bastila. I almost did it with g10 hk and g9 bastilla but died on boss with yellow health left on tier 5. decided to upgrade them just to avoid the headache and lottery rng. I have a nice pool of mods and almost all my team was 200+ speed with desired mods on them, so if you dont have that i imagine it being nearly impossible below that.
