All separatists unlocked - Best team for Padme 7*?

I have all Separatists (other than Wat) at 7*, but can't beat the event with my current roster. Have plenty of gear and a few zetas to improve my squads, but don't want to sink it all into droids only to find out Geonosians work better for example.

I've looked at some other threads but they generally seem to suggest things based on the best 5 or 6 characters they currently have, rather than the ability to have (pretty much) any squad.

Any advice would be much-appreciated!
