My Pitch for a RWBY x HSR crossover fanfic what are your thoughts?

I do have an idea for a crossover and how to explain certain elements in RWBY in Honkai Star Rail

1. The God of light and dark are actually emenators of the equilibrium and that it is because of this that the gods did not revive ozma on a whim but instead it was a necessary mandate to maintain equilibrium

2. The world of remnant was concealed by a faction of the enigmata that was long gone by the time the story takes place this is to explain why the IPC has not made any moves on the planet

Now there are plot points that I want to happen

1. In the beginning the astral express arrives on remnant as it is an undiscovered planet and they would want to increase fuel supply for travel

now this is where I would have trouble trying to integrate the Astral Express into the world of remnant like how do I integrate it to where they can meet the main cast of rwby? how do I integrate them into the story of RWBY?

2. The Jade of allying oath is used to summon the xianzhou fleet to assist them in the final battle by volume 8

3. Salem gets taken into custody and is taken into the shackling prison by the xianzhou which is suggested by the Astral Express because those guys have a lot of experience dealing with immortal beings.

4. Personally it would be my way of integrating RWBY into the world of HSR. Salem would join the Stellaron Hunters for the same reason as blade because the reason is Salem wants to divide humanity, summon the gods and they destroy the world and hopefully she would die as well. The Stellaron Hunters break out Salem and Elio recruits Salem into the Stellaron Hunters

5. My Favorite part is the interactions between the characters like how rwby,nora and march 7th interacting with each other as well as Dan Heng and Ren sharing their experiences with their respective teams

Anyways I would like to hear your thoughts about this
