What makes you think the "arrested development" Susan experienced in her early adulthood was permanent? If this is what you think -- I cannot quite make out why this essay caused you to despair for Susan?
Her character, throughout the series, is the one most likely to want to turn back or to wish she had never begun the adventure at all, so in keeping with this, she is eventually the one who does turn back. But in every other instance where her strength to go on failed, her brothers and sisters buoyed her up, and she continued on. Perhaps losing them so tragically will make her "grow up" in the true sense, rather than the silly way Lewis describes in the essay, of being overly concerned for "adult" things.
Have you ever noticed how, when someone loses a dear friend or family member in an untimely fashion, they are forced to reflect on spiritual realities rather than the trivia which mostly consumes our lives? What difference does the ringing alarm clock make, or the yakking TV, or the right shade of lipstick, when your parents and/or siblings have been torn away from you through death? At those moments, people are likely to reflect on what's real and what's eternal.
Although Susan's maturity was arrested at a silly stage and she began to value "adult" things just for the sake of being grown-up, in her moment of loss, there's a good chance she would come to her senses and turn back to her foundational reality, which is Aslan/Christ.
