[Harry Potter] How would George RR Martin write the Goblet of Fire?

The actual tournament itself.

We would get a couple of chapters from Cedric Diggory's point of view, to see his inner struggle with coming to accept Harry's sincerity. He would have the brief thought "Maybe Harry should have been in Hufflepuff" and then be ashamed at how he's wronged Harry in his thoughts. 

Cedric would come to realize that loyalty isn't just about house, it goes beyond that. He would resolve to try and heal the wounds between houses, try to bring Slytherin back into the fold. We would see him set out to fix the world by adhering to his guiding principles of loyalty and perseverance. We would come to love Cedric ever so much more than whining, sullen Harry.

Cedric's death would then be told from his own point of view.
