Yandere-chan's hairdo's hair ID is 1, just like Senpai's. So, if you put Senpai's hair ID on a female, it'll be yan-chan's hair.

(Unless you mean, like, the other hairs... Like the Hatsunny Meiok one or the Chiaki Nanami & Sayaka Maizono ripoffs)

The other ones goes vice versa, if you mean other students' accesorries then they have their own ID, if Yan-chan's accessories then it's pretty much impossible if you want to do it with the JSOn file.
