Making a very advanced rig from scrath

Hello everyone.
I need a very advanced rig for the face of my characters. what I'm asking is how to create one?
Questions:
1. Is it possible to add or remove as many rig as you need to MH characters?
2. Can you make rigs from scratch for MH characters? ( based on your prefered hierarchy and numbers )
3. What a good start for learning to edit/create bone for MH? Can you give the link or name?!
Thank you and have a nice day.
