This sounds really good so far. I'm excited to see where it's headed. :)

You've got a very interesting premise going here. I see a couple of confusing things, though. For one, girls generally stop growing at puberty, so why is Ginny taller than she was in fifth year? For another, when a man marries a woman, she can take his name legally in the US and, I presume, in the UK. However, her children are not considered his children unless he formally adopts them. Unless Narcissa's second husband adopted Draco, which seems unlikely since he was over 17 when his father died, Draco would still be a Malfoy here, and I suspect the UK has similar laws. I also have a difficult time imagining McGonagall sending out a letter saying no one who applies to be a teacher at Hogwarts will be turned down.

I mention these things because I think you have an interesting premise here, and things like this distract readers and make your story seem less credible. I like it and I am going to follow it - this is just my suggestion to improve something that seems pretty good.
