Star Trek will never move into gender equality as long as it sticks with the original crew. The only way to improve it is to go with a new crew, not go with the classic crew and try their best to give each character a moment in the spotlight, because than they're just spotlight characters.
So its just not possible for Abrams to produce a gender equality Star Trek movie because he's got Kirk, Spock et. al.
So its not Abrams fault at all, he just stuck with the wrong people (spotlight characters).
What is gender equality anyway, do you have to have 50% women, 50% of lines given to women (the Shatner equation) or is it possible for there to be gender equality without a strict quota?
