In a Young Justice and Justice League crossover fanfiction, character development can occur in multiple ways. Firstly, the less - experienced Young Justice members can learn from the Justice League's vast knowledge and experience. A character like Robin in Young Justice could gain new insights into detective work from Batman. On the other hand, the Justice League members can be inspired by the Young Justice team's energy and fresh perspectives. Superman might see the determination of a young hero like Superboy and start to reevaluate his own approach to heroism. Also, characters can develop through shared traumas. If they face a particularly difficult villain who causes a lot of destruction, they might all grow in their empathy and understanding of the importance of protecting civilians.
One great 'Young Justice Dimension: Justice League' fanfiction is 'The New Recruits'. It focuses on how new members are integrated into the team. The story has great character development and exciting action scenes.
One idea could be that the Young Justice team gets accidentally transported to an alternate dimension where the Justice League has turned evil. The Young Justice members then have to figure out how to reverse the situation while also evading capture from their once - heroes. Another could be a time - travel plot where the Young Justice team travels back in time and teams up with the early days of the Justice League to stop a threat that was thought to be long gone but has resurfaced in their own time. A third idea is that a powerful new villain emerges who can only be defeated by a combined effort of the Young Justice and Justice League, but first they have to overcome their differences in fighting styles and leadership.
A cool plot could be a time - travel related crossover. The Young Justice team travels back in time and meets the younger versions of the Justice League members. They have to work together to stop a time - traveling villain from changing history in a way that would destroy the future. Or perhaps there's a magic - based crossover where a powerful sorcerer is causing chaos. The Justice League, which is more used to physical threats, has to team up with the Young Justice, some of whom have magic - related powers, to defeat the sorcerer.
The experienced members of the Justice League would likely take on a mentoring role. For example, Superman might offer advice to Superboy on how to better control his powers. Batman would probably be more cautious about involving the Young Justice team in dangerous missions, while the younger heroes would be eager to prove themselves. Aqualad could learn new underwater combat techniques from Aquaman. This would create a dynamic of growth and learning between the two groups.

One idea could be that the Young Justice team has to prove themselves to the Justice League during a major alien invasion. The League initially doubts their abilities but as the battle progresses, they see the unique skills and teamwork of the young heroes.
I'm not sure about specifically 'famous' ones just for this concept. But there are many talented fanfiction writers in the DC universe fanfic community. Some writers might be well - known within the circles of those who are really into Young Justice and Justice League crossovers. They often have a unique take on how the Justice League would interact with and watch over the Young Justice team.
In such a fanfiction, there might be a big threat that requires both teams to combine their skills. The Flash could race with Kid Flash and share some speed - related tips. And Wonder Woman could train the female members of Young Justice in combat.
They might be really surprised. Some fanfictions could show their characters in very different ways than they expect. For example, they might see relationships between characters that they never thought of in the official story. It could be both amusing and a bit strange for them.
