I suppose that's possible, though for me it's a pretty big leap to go from cheating on homework to visiting dark alleys for magic crack. Not to mention that "Gingerbread" sets up the cliche that kids playing with magic are dangerous and up to no good, and then knocks that cliche right down by having Willow, Amy, and Michael's casting be completely benign, simply a way of figuring out a birthday present for Buffy.

But like you say, we can probably interpret Amy as having control issues, so I guess it's not so far-fetched.
