I'd definitely use the original eight members on the team, plus the addition of Cyborgirl from the Jimenez era. Creatively, I think there are a lot of ways to build the characters relationships together, in positive and negative ways, with the range of characters, their personalities, their abilities, and their past associations with Diana and each other.
