DC showed they can make more WW characters like donna or they can push wonder girl up, they made warkiller a male WW. out of the amazons Artemis was better amazon then WW, but WW was a better WW then Artemis, and she really is not the best, and at the same time she is, WW had to work to gain that power and level she is on, unlike superman and others who just get the power from the start and get pushed up. even in the new 52 WW she still has to work to get to the level she is at now in the JL comic. Passing test all her life being pushed to be better and better. she had to work so much harder since she is a woman, so i feel yes she can be on superman level of power, she had to work hard and pass many test to get there.
