I have often thought about building some kind of an adapter for the galley outlet with a screen for debris and a 12v pump attached. Run a line to the toilet supply line with a quick connect and couple of ball valves to switch between sources.
After a couple of days of using the kitchen sink, one could easily supply the toilet with that water instead of fresh water.
You could also use the black/grey water outlet but would want to be sure you didn't pull the wrong waste gate valve. By using just the galley, you wouldn't need to worry so much.
