Hogwarts camping

what if u do y/n as Harry's sister during the final battle but instead of harry dying it's y/n and you could start the prologue as yk that song where it's like "I'm ripping all the skin from off my bones, prepared too sacrifice my life and I'd gladly do it twice" and y/n and Voldemorts spells collides and in the end y/n wins but is terribly hurt. Just a suggestion

Tell me some ideas for a new talkie!
