Using acoustic transducers it maybe possible to create a small region of thicker air underneath a blimp and use that patch as a platform of air to float on while blowing ever so slightly low pressure air underneath the blimp like a hover craft. Although this idea sounds like a long shot it can be done by use of a screen, which shoots the directed frequency waves into the waves created by the acoustic transducers. In fact it maybe possible to place the acoustic transducers on poles, which hang do.
