One idea could be to explore an alternate universe where Rick and Morty swap personalities. Morty becomes the super - intelligent, reckless one, while Rick is more timid and hesitant. Another could be a story where they get stuck in a time - loop within a particularly strange dimension and have to figure out how to break free. Maybe a fan fiction where they encounter a version of themselves from the future who have become the rulers of the multiverse.
Well, for 'rick and morty displene fan fiction', you could write about a situation where Morty discovers a new alien species that is immune to Rick's technology. This would force Rick to think outside the box and use Morty's more naive but sometimes brilliant ideas. Or perhaps a fan fic where they accidentally create a portal to a dimension full of their doppelgangers, but these doppelgangers have all their worst traits amplified, leading to a chaotic and humorous adventure.
Beginning a 'rick and morty displene fan fiction' can be done in several ways. You could start by creating a new character who interacts with Rick and Morty. This character could be from a dimension that Rick has never visited before. Say this character has a special ability that Rick is intrigued by. Write out their first encounter, how the character challenges Rick's beliefs or how Morty is both scared and fascinated. Another way is to take an existing episode and rewrite it from a different perspective. For instance, if there was an episode where they visited a water - based planet, you could rewrite it as if it was all a dream Morty was having, and then explore how that changes the events and the characters' actions.

Maybe a fan fiction about Rick and Morty getting stuck in a time loop and how they try to break out of it.
