Battle of Z xbox 360 online achievement help

[Bardock God of Time]

I'm missing just one achievement in Battle of Z, it's the one where you win a Battle Mode match with 4 different Gokus.

I've tried making multiple sessions on Trueachievements but we never get enough people. I mean, I've gotten a team of 3 with the Fixed setting but the random CPU is never who we need.

If anyone has the game and be willing to help, I have a session tomorrow but I'll probably end up having to make another session further out.
