I don't think you can do it yet. Bane is really easy to kill and your tanks aren't built up enough that they can take more than a hit or two. I'd keep starring Boba Fett and max out his abilities. You'll need him to be as powerful as possible since he's your main damage dealer until you get raid Han Solo. It's also worth putting some second or third tier mods on your scoundrels to increase their speed and durability. You'll eventually want everyone on your scoundrel team at level 80+ for the 4th tier, so it's worth leveling them as well.

The simple answer is that you're not ready yet, but if you keep working on your scoundrels, you could be able to handle the next one.
