I'd love to something that redefined what a Jetpack is, instead of using the old IC2-esque Jetpack. Something that creates Negative Mass around itself in order to create a bubble of what is essentially reversed gravitational fields surrounding it. This would allow ascension, descension, and hovering with justified logic behind it. We don't know what's out there, so it's entirely possible there's something with a Negative Mass out there (I mean, stranger things have happened, Black Holes come to mind).
