The Smenkhkare/Zannanza version garners little support among Egyptologists. With the presence of Tutankhamun, Miller points out Meritaten "would presumably have needed the backing of some powerful supporter(s) to carry out such a scheme as the tahamunzu episode, one is left with the question of why this supporter would have chosen to throw his weight behind such a daring scheme". For the plot to succeed, it assumes the young Meritaten with her co-conspirators successfully deceived Suppiluliuma and his envoys (for there was a royal male - Tutankhamun - though not actually her son) and that the plot remained secret during the period of letter writing and Zannanza's travel to Egypt. It assumes the other elements of Egyptian society remained idle with a female interregnum on the throne and a royal male standing by while this played out. On the Hittite side, it assumes that Suppiluliuma was not only willing to risk the consequences if the plot were uncovered, but rather than merely shrewd, Suppiluliuma was ruthless in the extreme and willing to risk the life of his son on a precarious endeavor where he suspected trickery.
