Cortana's "sister" is Kalmyia, and she is erased in first strike when the covenant break into the ONI Castle facility
All of cortana's software intrusion programs were tested on Kalmyia first, and Dr. Halsey refused the order to destroy any cortana prototypes. So in a sense, Kalmyia is cortana's older sister.
It would be stupid if the chief got a new AI, because there are probably only a few AI's left after the covenant attack, and then the chief would have no reason to try to get cortana back
