I'm not so sure that would even be be necessary. IMHO, she tolerated the menial drudgery of endlessly boring procedures, hearings and blather, just 1 of 50, with no absolute power of her own, only because it was a necessary step to her perceived birthright, the Presidency. I suspect she'd say she was going to run again, just for appearances, but something would "come up" 6 months out, in time for a democrat to be appointed to fill the vacancy and have an incumbent solidly in place for the election. Meanwhile, she will have arranged some more suitable position for herself, such as Emporer or Secretery General of the Universe.
I think your assessment is spot on -
