Nope, not if she came back in the same form as Bob, he has no free will, it isn't clear yet that Bonea has free will.
Bob has no free will because he has no soul. Murphy still has her soul. That is the meaning of walhalla, Hades or staying behind as a shade, with or without a wooden skull apartment.
This is not about coming back as a black court vampire or something like that. Walhalla is a genuine afterlife. It is Murphy who resides there.
So what a wonderful thing for Murphy.. Not a living being anymore, it is doubtful that she'd still have the free will.. Be careful what you wish for..
That would not be Murphy. It is all about her soul. As long as she has her soul she has her free will just like Harry had or her father has.
Uriel was pretty clear for a change. It is about your soul.
If you have your soul you can theoretically return to life given a suitable body.
We are talking about Murphy, not some ghost of Murphy otherwise she would not be back and the whole discussion would be about something totally different. She either comes back with her soul or she does not come back.
