If Brandon Sanderson Wrote Other Authors' Novels

[Authorspren]

I saw that there was a topic about other authors writing Cosmere novels, so we're doing the opposite. What if Brandon Sanderson wrote other authors' books or movies? Here's a couple examples:

Harry Potter:

The magic system of the world would be more defined and be related to the number four, with unique magic arts corresponding to each Hogwarts house. Every wizard would only be talented in one type of magic, giving them limits to their power. Harry would have the same "Boy who Lived" backstory, although the reasons for his survival would be more than just plot armor. He'd also have actual trauma from being an orphan raised by an abusive family, and this would have consequences for the plot.

The Wizard of Oz:

Dorothy would be a normal girl who accidentally Worldhopped to a strange planet with a pair of Invested shoes. She'd be fully aware of the powers of her Invested shoes but have no idea how to control them. The Wizard would be a helpful scholar with no actual abilities who helps teach Dorothy about the shoes, and the Wicked Witch of the West would be an Invested tyrant looking to steal the shoes' power.

Starter Villain: Dorbev would be a morally complex character who wants to run the Convocation for the greater good, Til would be saved from death by Charlie in the climax, and there would be at least a little time travel.

[Hmmm lies she/her]

Oooh what about The Wheel of Time oh wait...

In all seriousness, for LOTR there would be no details on languages, and everything Gandalf does would be completely explained, and the ringwraiths would likely be revived to help fight Sauron, who would be a morally ambiguous character.
