Hm. I did not properly account for that. Specifying "girl-child friend's counsel and restraint" and "that she is a part of this world for you to care about" is definitive in that Voldemort intends to restore Hermione as Hermione. For my theory to work, this would have to be a long-term gambit that Harry has made immediate; but this would not explain why Voldemort has made so many tactical, i.e. short-term, errors. So I agree this is strong evidence against my prediction. New confidence: 1%.

EDIT: If someone can explain how to add strikethrough to my original confidence, that would be helpful.
