Iphone X AR Facial Animation Kitboy example Question

Question about the AR Facial Animation project provided by EPIC with the Kitboy.

What is the best workflow for getting all the Anim Blue Prints that are currently on the kitboy onto a new custom characters. Is it recommend to copy and paste or create it from scratch?

The face ARPawn seems like it could be used for for multiple characters with minor editing to the Blue Prints. Looks like there is only a KitboyReference that needs changed. But the blue prints that are on the kitboy seem like a lot. So whats the best way to get all those blue prints onto another character?

Thank you!
