I love this story. It's book 7 done the right way. You'll have to drift from canon more sooner or later, which is fine by me since I didn't like canon too much. I don't see Ron taking the growing relationship between Harry and Hermione very well and staying with them on the adventure. He's too hot headed, so it looks like you'll reach the point of Ron leaving them, which will mess up the entire original plot. Of course it all depends on how you do this. I'm looking forward to more of this and seeing H/Hr getting together. Hopefully it won't take the whole story to reach that point. :-)
