One idea could be the clones having unique abilities different from the original edo tensei summons. For example, they might be able to combine jutsus in unexpected ways.
A great plot in 'naruto edo tensei fanfiction' might be an alternate universe where the edo tensei is not a jutsu used for combat but for a more peaceful purpose like resurrecting historical shinobi to teach the new generation. This could lead to all kinds of cultural exchanges and unique training sessions for characters like Naruto and his friends. Also, a plot where edo tensei characters rebel against their summoners due to having their own wills and agendas would be exciting.
A great plot could be that Kushina's Edo Tensei resurrection is only temporary. Naruto has to race against time to learn some important lesson or power from her before she disappears again. This could add a lot of emotional depth and urgency to the story as Naruto tries to make the most of the time he has with his mother.
Another plot could involve the Edo Tensei characters crossing over into a different anime world. Maybe they enter the world of One Piece. There would be a clash of powers and ideologies.

Well, a plot could involve Naruto in Edo Tensei form being able to access new and unique jutsu that he couldn't in his living state. Maybe these jutsu are related to the afterlife or some forgotten ninja arts. This could lead to him teaching the living ninjas these new techniques to help them in a coming war. Also, his Edo Tensei presence could stir up old emotions among his friends and enemies. His friends might be conflicted about fighting alongside a dead Naruto, while his enemies might see it as an opportunity to finally defeat him once and for all. Additionally, Naruto in this form could be the key to unlocking a hidden power within Konoha that was lost ages ago.
One idea could be exploring the relationships within the Senju family that were not fully shown in the original Naruto series. For example, how the Edo Tensei - resurrected Senju members interact with the living descendants. Maybe they could pass on long - lost jutsu or wisdom.

One idea could be exploring the backstories of the Edo Tensei - summoned ninjas in more depth. For example, you could focus on the relationships they had before their deaths and how those relationships are affected when they are resurrected.

One possible interesting plot could be Madara, in his Edo Tensei form, somehow regaining his full power and challenging Naruto not in a fight to the death but in a battle of wits.

For example, Naruto could use his talk - no - jutsu to try and convince Madara that his quest for power has only led to destruction.
In some edo tensei Naruto fanfictions, the rules of the edo tensei jutsu are altered. This could lead to some really creative plotlines. For instance, the resurrected characters might be able to retain their memories more clearly or have different abilities compared to what was shown in the original series. This allows for new and exciting battles and interactions within the Naruto universe.
