What team without Grievous should I farm and gear to unlock 7 star Padme in 1-2 months (next return)

I was thinking of going GG lead, b2, droideka, assajj, and Sun fac/dooku/soldier.

From what I've heard b1 is actually a detriment to the event. My GG is like 4 star g1. It's going to be like third or fourth go around for me to get padme 7*.
