Or move the cloud cities to one of the gas giants (presumably where the water is coming from anyway, or at least one of their moons, so the interplanetary transport infrastructure would already exist at this point.

    The water should be coming from the comets or at worst the asteroid belt.

    Lifting a city out of a gravity well only to deposit it on Jupiter or Saturn, not only is a waste of resources, it won't work.

    Mars isn't a viable terraforming candidate because it has a mass of about 1/3 that of The Earth. No human can live there for any extended period of time.

    The problem you have with all of the gas giants is the opposite issue. Once the city achieves boyancy, as everything that falls into a gas giant will, it will be so deep into the gravity well that humans would be crushed.
