Quick Transmigration: Drawing a Role to Play in Everyday Life

Any Novels Where the Protagonist Can Transform into Anime Characters?

The protagonist can choose a character to transform into at any time and use that character's abilities. Not just a roleplaying story where they only get one ability.

Stories About Playing Female Anime or Game Characters, or Transforming Into Them

The Protagonist Has a Role-Playing System

Preferably with a smaller cast, so each character gets to play their role for a while.

Looking for a New Cosplay-Template Novel, Preferably Featuring Honkai: Star Rail, Genshin Impact, and Honkai Impact 3rd

I want something like "Honkai: Star Rail, but My Cheat Lets Me Transform into a Honkai Valkyrie". There are already way too many stories about national destiny and rule-based horror games. I'd prefer one where the characters cosplay in the real world. I hope an author will come up with something new, or at least write more stories where a System lets the protagonist transform directly. Being able to turn into multiple forms would be great, of course.
