What about Francesca? We didn't explore her character much. She chose to leave a safe, well-paying job with the DMV to work with Saul. Why? She was deeply entangled in Saul's illegal doings. I'm sure these writers could write a good story of her breaking bad. She uses the remaining contacts from Saul and starts her own illegal operation in a different state, and maybe not meth. You could introduce new characters, and you would also have a female lead protagonist.
