After the movie, can Nikki avoid jail if Saul Goodman helped her?

Yeah. Stupid question that just popped in my mind. 3 dead. 2 killed by her. No way she is avoiding the court. So what if after the film ended, she cries and then eats something and cleans herself. And calls Saul Goodman. We are assuming he is a practicing lawyer at this moment.

Can Saul Goodman save her from getting life in prison or avoid her getting prison at all?
