I really like 'A World United'. It takes the magic systems from 'acotar' and 'throne of glass' and creates something new. The author does a great job of making the fanfiction accessible to both new fans of the series and those who are very familiar with them. It has a great balance of action, romance, and mystery.
One key theme is friendship. Azriel often forms deep and meaningful friendships with male characters in these fanfictions. Another theme is self - discovery. As he interacts with different male counterparts, he learns more about himself and his place in the world. Also, loyalty is a big theme, as Azriel and the male characters in the stories often have to prove their loyalty to each other.

It could be that fans are writing mature - themed stories based on the 'acotar' universe.

Perhaps a crossover where the magic systems cross over. The valg from 'tog' could somehow seep into the world of 'acotar' and the characters from 'acotar' have to learn about the valg and how to combat it using the knowledge that Aelin and her crew have from 'tog'. This could lead to some really interesting battles and alliances.
Maybe a character travels forward in time and sees a dystopian version of the ACOTAR world. They then have to go back and try to prevent the events that led to that future. They could face many challenges along the way, like not being believed or having to work against powerful forces who benefit from the future they saw. It would be a race against time to save their world.
