They could interact with the historical figures in 'Hamilton' in a modern and unique way. For example, Usnavi could meet Alexander Hamilton and they could exchange ideas about building a better future for their communities. Maybe Usnavi could introduce Hamilton to the concept of a tight - knit neighborhood like in 'In the Heights' and how it can be a force for positive change.

And a third idea could be a mystery plot where strange things start happening on the ranch and the characters have to figure out what's going on.
One idea could be Android 21's struggle to fit into a world that fears her. She has to prove that she's not a threat and tries to make friends. Another could be her discovery of new powers and how she uses them for good. Maybe she teams up with other characters to fight a common enemy.
One idea could be Vampirina making new friends in the human world who are initially scared but then come to understand her. For example, she could join a school club and have to prove that she's not a threat.

A great plot for DuckTales 2017 fanfiction could be an alternate universe story. In this universe, Scrooge never became rich and the Duck family has to struggle in a different way. It could show how their relationships and personalities would change without the wealth. Also, a story where the nephews get to run the business for a day and end up getting into all sorts of hilarious and dangerous situations. Maybe they make a deal with a dodgy character that seems good at first but turns out to be a big problem. And then there could be a fanfiction about the origin of the Money Bin, with Scrooge having to face many challenges and enemies to build it.
