There does seem to have been a general shift in royal properties among the
royal ladies late in Akh's reign which may simply have been due to a simple
redistribution after the deaths of Nefertiti and Tiye altered the ladies
relative standing.

Kiya apparently came to new prominence, though still ranking behind the
royal daughters, and the two elder princesses divided their mother's
duties between them. However according to the talatat neither was a queen
meaning Akhenaten did not marry either Merytaten or Ankhesenpaaten. The absence of a co-regent as late as year 16 does imply that Smenkhkara was a successor rather than a co-regent and married Merytaten in Akh's last year if not after his death.
