Can I beat Thrawn 7*

Possibly. Your mods are not the best and level 85 really makes a difference, but they aren't horrible. All of your characters are gear 9 or 10. Most people do it gear 8. Assuming you keep leveling them since this post, and the Thrawn event comes out in a week or two from now, you should be able to hit lvl 82 or 83, and after that, if you can get a little better mods I think you should be fine.
