She would be super cute with rabbit ears! And she could even have a giant pocketwatch to swing at people like a pendulum type weapon.

And yeah I was trying to hunt down what stories Father Time is in, but... Guess he's kind of more like those fictional figures like the Mother Nature and Boogeyman where rather than a particular story origin, the figure appears in various depictions. I think Chronos mythos is the closest origin...

But yeah, you could still incorporate a lot of "time" elements with the White Rabbit, so it could still work well!
