Make animation blueprint to use a new skeleton

Hello, I was wondering if it is currently possible to replace an animation blueprint’s skeleton with a new one. Im using the RPG toolkit from the Unreal Market place and everything is already set up with its animation blueprint but need to use a different skeleton. Easiest way to fix this is to just replace the skeleton but cant seem to find out how, least not with a way I understand, assuming what I found are applicable answers at all.

Thank you
