I'd place the upper limit to what handwavium an lift to the point where you are moving the planet instead of lifting off. Sure it would be a huge projet needing thausands of people and much more handwavium than exists in all of fenspace, but it's theoretically doable. much like we could build an interstelar spaceprobe without handwavium, it's just too expensive to be feasible.
Edit: some back of the envelope show something along the lines of lake mead (the lake created by the hoover dam) as the aproximatte volume needed to lift a small city. I'm not sure if I can explain how mindbogeling huge that amount of handwavium is. Think how long that will take to grow, and how long it will take to apply...
E: "Did they... did they just endorse the combination of the JSDF and US Army by showing them as two lesbian lolicons moving in together and holding hands and talking about how 'intimate' they were?"
B: "Have you forgotten so soon? They're phasing out Don't Ask, Don't Tell."
