Be careful what you wish for...

I wish Legolas was still alive, still living in "Middle Earth" (which now is what we call "Planet Earth") and posting on the 'downs

Your wish is granted. But when it was revealed that The Barrow-Wight was Legolas mass chaos erupted. The news reached the New York Times with the headline, "Stern forum moderater is Legolas." His house was mobbed by fangirls and others who wanted to talk with a member of the Fellowship of the Ring. But he was not there. He had fled to the woods of West Virginia. At least the Balrog wing debate was solved because of The Barrow-Wight's vote in the Balrog wing poll. But The Phantom became the new moderater and the members yearned for the days of The Barrow-Wight.

I wish Saruman hadn't turned bad.

Your wish is granted. He takes up Tennis instead of becoming evil. He turns all of Isenguard into a giant Tennis stadium and plays endlessly against Gandalf and the other Istari. Gandalf is distracted by the final of the Saruman Cup and does not warn Bilbo about giving away the Ring and so takes it to Rivendell.
Sauron attacks Rivendel and Bilbo is cast out for being selfish. The Dark lord regains the Ring and launches an all out attack on Middle Earth. Gandalf doesn’t finish his game against Saruman and returns to Valinor and sulks.

I wish The Balrog had decided to be civil and not tried to kill the Fellowship. Offering them a cup of tea instead.

Your wish is granted. The Fellowship decides to have tea with the Balrog. Their stay lengthens to a week, and then a month. Frodo quickly becomes good friends with the Balrog, impressed by his charm and wit. The Balrog then declares that he is actually a she, a sister of Arien (who, after all, is also a spirit of fire, albeit uncorrupted). Frodo's affection turns to love, and they get married on top of Zirakzigil, in a ceremony done by Gandalf.

When Frodo was about to put the Ring (yes, the One Ring!) on the Balrog's finger, a Nazgûl takes the Ring, Gandalf suddenly uncloaks, and Pippin throws himself in next time. Utter confusion!

I wish Huan just laid the smackdown on Sauron.

Granted. He lays 'the smackdown' on Sauron. 'The smackdown', of course, being a secret of Huan's for making toasted cheese. He lays the cheese on wolf Sauron who accepts this gift and they share it with Luthien. She turns out to be lactose intolerant and swells up like a balloon and floats away for some reason. Huan and Sauron become best friends.

I wish the three Troll's mothers had appeared in The Lord of the Rings for revenge!
