I strongly suspect that a ‘Mother’ is a realised consciousness manifesting as a person, and not a literal person. Daughters and Granddaughters are people but Mothers are just consciousness. 

So becoming a ‘Mother' means that the consciousness of the realised granddaughter merges with all the other mothers that came before. So, for example, 'Mother Artifice' is not just the person/granddaughter who became Mother Artifice but rather the aggregate consciousness of all the other Mother Artifices that came before them as well. 

So if Dot were to become the new Artifice their consciousness would merge with the present Artifice and ‘Mother Artifice’ would no longer manifest in the form/personality that he presently does - the form that Everett is attached to. Because Everett is super emotionally attached to Mother Artifice, she blames Dot for the future loss of her loved one, leading to all the explosive emotions and hatred. 

This could also explain a lot about Artifice and Cleo’s confrontation in episode 14. Artifice warns Cleo that Dot will no longer being the same person after they become a mother, so it is effectively useless to form a relationship with them. And Cleo retorts that she sees Mother Artifice having relationships with people and does not understand why Dot would not be able to as well.
