It should be smaller than ISS. IIRC, ISS has three solar arrays and two radiators. DGX is about the size of a fridge. Let’s add two more fridges worth of infra for solar and radiator. Maybe another fridge for comms. But these three fridges replace all the modules of ISS. It’s still gonna be about 6 (maybe up to 10?) tons of mass to lift. But Starship can do 100-150 tons to LEO so might be doable.
