I think it comes down to how you value relationships. I don’t want my family replaced, so replacing one of them with someone in a similarly valuable mental state might be equal in terms of their mental state, but because you’ve broken a relationship I value, the total utility has dropped. Other than this, I’m not sure I can see a relevant difference between extension and replacement.
