Pichu over Pikachu Model Import

[MewtwoFanz]

Hi, I want to request a Pichu over Pikachu Model Import. Here's a link to the model I want over Pikachu: https://www.models-resource.com/3ds/pokemonxy/model/8618/
I want it over Pikachu, but as exra character slots, NOT replacing Pikachu itself. I Also want Nametags and CSPs, Character Select Icons and Stock Icons, if possible. Thanks to anyone who can do this.
