I think this is fundamentally impossible, win loads are powerfull enough to ouright warp and destroy giant ground based cranes like they were tissue paper if the operator makes a mistake, like lifting oart of a stadium roof in high wind. there are scary videos all over youtube. Those things and made of hige steel girders.

This is going to be a light, fragile airframe with much bigger 'sail' in the form of the airship - its the size of a stadium.

Nothing short of a rocket engine will be able to keep it in place.
