ROM Hack [Help] Editing Pokemon Sun and Moon's models?

[TrueMrHacker]

Hi there!

Does anyone know of a way to edit the models in Pokemon Sun or Moon?
If there is a thread somewhere explaining how to do it then please give me a link.

I want to find a way to edit the models in the games so that I can possibly make a "rom hack", my ideas for it are bland but it's gonna be a long project and I literally have no life so it might be fun.
The only models I want to edit are the trainer models.

Thanks in advance!
