I expect this is too expensive to be worth it. but instead of a whole second water system, it’s theoretically possible to use gray water from bathing and showering for flushing.
On second thought, this might actually make sense for apartment buildings and hotels, since some gray water could be stored and sent downhill for flushing—you wouldn’t need a pump in the bathroom.
