Do you mean the CG "recommended" GP value? Or are you talking about recommended values for specific stats (like "X many Health points") created by some non CG guide to the event?
Because I can tell you that the CG recommended GP value is worthless. Most folks who beat the event have 2 relic toons and the other 3 at g12. You've got one relic toon, Ventress, and no relic droids, and one of your droids is still g11.
I'm not saying you can't beat it, but I'm saying you shouldn't expect to be able to beat it without trying again and again and again for the best possible RNG.
My way isn't the best way, it's just the way that works for me, but I play for fun, not headaches, so I would Relic your B2 and your B1 then go back in and finish the event in just a few tries, 25 minutes tops.
Compromise position might be to get B1 up to relic, and all your other droids up to g12+2 or +3, making sure that you give each droid what they most need (Magna being a tank gets health gear, etc.)
It will take you more attempts than if you had both B1 and B2 at relic (they're a great tag team) but it won't take you 96 hours of obsessive button pushing. Expect to be at it for 30 to 60 minutes, less if you get lucky off the bat, but it's always possible it will take longer than an hour.
