Lord Potter-Peverell-Black, His Neko, & the Marriage Contracts

What if the Polyjuice Potion with the cat hair that Hermione drank during their second year was permanent? What if the only parts of the transformation that Madam Pomfrey was able to reverse were the extra sets of breasts, whiskers, muzzle, and the fur that covered her entire body; leaving her with fangs, a tail, cat ears, claws that retract back into regular fingernails, slitted pupils, and a sandpaper-like tongue? What if the only way that no one would find out was with a collar/necklace that was charmed with a glamour? What if the only other people who knew that her feline attributes were glamourized other than the Hogwarts staff and her family were: Harry, Tonks, Daphne Greengrass, Luna Lovegood, Teddy Lupin, and Lavender Brown? Also, what would life for Harry have been like if Peter Pettigrew was caught, Sirius was exonerated, and able to adopt/raise him during the summer before their fourth year? What if Harry becomes Lord Potter before his fourth year and finds out that he has two marriage contracts tied to him?
