Forgive me if this has been said before (I am a lowly college student, and self-proclaimed expert on NOTHING) but... if mtdna tests could be done on Tut's mummy, and the mummies of his supposed children (if Hawass even knows where they are) it may shed light on why he became king. Supposing for a moment that such testing showed Tut and his wife shared mtdna; that's some evidence for both being children of Nefertiti, and would indicate that Tut was Akhenaten's son, and not his brother. I know this isn't the most popular interpretation of the evidence- but it's a testable hypothesis.
Testing all the bodies could reveal heretofore unpredicted relationships in the royal house. It could resurrect unfashionable theories (like the 'heiress' theory) or help us create new models of royal lineage- just what was considered a 'royal bloodline' when. While this might not give us definitive answers as to which mummies we've got, with enough bodies to examine, we might get a picture of how families move into and out of the royal line over time.
