Could be. . .they realized that Eve's character actually fit well into an existing character, and made the change for the sake of improving the story.
So possibly Rand, Chapel, Carol Marcus, Elizabeth Dehner, or any other blonde. Only because of the hairstyle, I think Dehner.
Chapel is a possibility based on the blue uniform. However, the hairstyle certainly suggests Dehner, who also wore a blue uniform.
Rand wore red, and Carol Marcus wasn't even in Starfleet.
