I hope the Amazon show doesn't depower Wonder Woman. A crossover would be nice, but I would rather have a Wonder Woman with superpowers and mythological allies and foes than go for the Arrow 'realism'. Without the magic, what's the point of doing a Wonder Woman show? CW already has Nikita. I don't see how a powerless Wonder Woman show is going to be that much different, or find someone as good with action as Maggie Q is.
They could base it on the Wonder Woman stories of the seventies.
