A popular pairing could be Dipper and Steven. They are both curious and adventurous, so fans might like to imagine them exploring new worlds together. Their different backgrounds would make for an interesting dynamic.
Another pairing that might be popular is Ford from Gravity Falls and Pearl from Steven Universe. Both are highly intelligent and have a lot of knowledge in their respective fields. Their interactions could involve deep discussions about science, magic, and the nature of their different universes.
The unique worlds of both shows. Gravity Falls has its mysterious and spooky elements, while Steven Universe is all about love, acceptance, and gem magic. Fanfiction allows fans to explore these worlds further. For example, in Gravity Falls fanfic, people can create more adventures for Dipper and Mabel. In Steven Universe fanfic, more relationships between the gems can be explored.
One interesting crossover could be the characters from Gravity Falls and Steven Universe teaming up to solve a mystery that involves both the Gem world and the strange happenings in Gravity Falls. For example, Dipper and Steven might combine their knowledge of the supernatural to figure out a new threat.
Definitely Steven and Dipper. Steven is so open - hearted and has a positive outlook, while Dipper is more skeptical and curious in a different way. Their different personalities could lead to some really interesting exchanges as they try to understand each other's worlds.
One possible plot could be that the Gems come to Gravity Falls to investigate some strange energy readings that are similar to their own gem powers. They meet Dipper and Mabel, and together they figure out that there is a connection between the two worlds' magic.

Definitely Dipper and Pearl. Dipper is always eager to learn about the unknown and Pearl is full of knowledge about Gem history and technology. Their conversations could be really interesting as they share their insights on different mysteries.
I think Tommy and Dipper would be a really interesting pairing. Tommy is the fearless leader among the Rugrats, and Dipper is always eager to solve mysteries in Gravity Falls. They could combine their skills and curiosity to explore new areas in Gravity Falls or figure out some strange happenings. Another cool pairing could be Angelica and Pacifica.
