If there are two Shabbos Chanukahs, the 2nd will be miketz.
Move it up a day (meaning if Chanukah starts on Fri). It is Motzei Chanukah which is Miketz.
Nothing to do with a leap year.
Think about it this way, Beraishis will always be the week after Simchas Torah.
Leap year will only start affecting the parshios after Mishpatim.
