#3 Stephanie McMahon
This is not necessarily a return per se, but it would be quite interesting. Stephanie entering the Women's Rumble would be highly unlikely, but it would play into Stephanie's "historic announcement" that she made earlier this month.
In 2014, Stephanie had an entertaining program (and match) with Brie Bella, showing that she has the capability to pull off good interactions with some of the current female talents. Many fans online complain that she does not receive proper "comeuppance", but it is hard to do so when WWE does not want any intentional man-on-woman violence. If Stephanie was in the Women's Rumble, it would help plant the seeds for feuds down the line.
