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.
Well if you can fill an ocean on Venus by the the time the cyanobacteria makes its atmosphere lose density, or even a great lake, then the cloud cities have somewhere to land safely.

You can’t take this away from me.
