One possible plot could be that the RWBY team is on a mission in a forest that has a dark history similar to Crystal Lake. They start to notice strange things happening, like people disappearing. Then, they encounter a masked killer similar to Jason. They have to use their skills as huntsmen and huntresses to fight this new threat while also trying to figure out the mystery behind the killer.
Well, a cool plot could be that there's a portal that opens up and transports the RWBY world into the Friday the 13th universe. The characters then have to figure out how to get back while dealing with the killers and other threats in that world. Weiss could use her glyphs in creative ways to combat the danger.
One possible plot could be that the vampires from Twilight somehow end up in the world of Friday the 13th. Maybe they get transported there by a strange magical event. The vampires' powers would be a new and terrifying element in the already spooky Friday the 13th setting. They could either be enemies of Jason or form some sort of uneasy alliance with him.
Maybe Bree is a journalist who is investigating the rumors around Crystal Lake. She gets more than she bargained for when she encounters Jason. As she tries to escape, she discovers some secrets about the place that could potentially stop Jason once and for all. Along the way, she meets other survivors and they all work together to fight the horror.
Yes, there are some interesting ones. You can start by looking on fanfiction websites like Archive of Our Own.

However, the quality can vary a great deal, so it's best to read reviews or summaries first.
One possible plot could be that Jason's sister discovers the truth about her brother's actions and tries to stop him. She might have some hidden powers or knowledge that could be used to put an end to the killings.
Ruby's speed might increase even more due to the sense of danger from the Friday the 13th elements. She could be constantly on high alert and her scythe attacks could be more erratic and fast - paced.
It could be a really wild and spooky combination. Picture Hogwarts during a Friday the 13th. Maybe the Forbidden Forest becomes even more menacing, with strange and dark creatures emerging that are a mix of the magical world of Harry Potter and the horror elements of Friday the 13th. The students might have to deal with cursed objects that seem to be influenced by the unlucky day.

The '4th meets 10th fanfiction' might be a story where the 4th entity has a certain goal or mission and during that journey, they cross paths with the 10th.
