Idea for endgame lake mod

Anyone know if something like the following exists?

My idea is that once you have full Atmosphere and Water levels any lakes that have been excavated and completely filled, begin pumping water back into your water system.

There could even be a research-able technology for this that would act as a building upgrade for the lakes you create.

It just seems silly that at the end of the game you are still relying on Moisture Vaporators to farm all your water, some of which has to be pumped into lakes, even though it's regularly raining as it does on Earth. Endgame lakes should convert into your primary sources of water.
