I wish Samwise Gamgee had been a Middle-Earth renowned soccer player

Your wish is granted. Samwise Gamgee becomes the greatest soccer player ever-known, he even surpasses the great tales of the legendary David Beckham. But, Sam now has no time to fiddle around and be Frodo's servant and companion so when the decision comes and Gandalf tells Sam to travel with Frodo. Sam, being so great and mighty tells the old fool to buzz off and Frodo dies before he meets Tom Bombadil and Sauron conquers Middle-earth.

I wish Denethor was Isildur's heir and Aragorn was the Steward of Gondor.
