In 1988, James P. Allen proposed that it was possible to separate Smenkhkare from Neferneferuaten. He pointed out the name 'Ankhkheperure' was rendered differently depending on whether it was associated with Smenkhkare or Neferneferuaten. When coupled with Neferneferuaten, the prenomen included an epithet referring to Akhenaten such as 'desired of Wa en Re'. There were no occasions where the ‘long’ versions of the prenomen occurred alongside the nomen 'Smenkhkare', nor was the ‘short’ version ever found associated with the nomen 'Neferneferuaten'.
