Sorry for the phone paint just a simple idea

Yellow containers - bucket on top with res below
White is net pot
Blue is water
Red is water pump
Green is pvc drain (also plant color)

Let us know how it works out in the real world. Looks like you could lose a lot of vertical growing space with the pot on top of a tank, probably better to just put the net pot / plant in the bottom tank and call it DWC.
 
I was just wanting to do something that wont need a air pump but still stable enough for a good size plant unlike nft Where the holes and cups aren’t really that big or supportive.

Then I saw a octopot and thought why not keep roots in top allow a water pump in bottom with drain for continued flow

Or what about instead I put a toilet water release in bucket with float so when water fills to certain point it drains allows air then refills and dumps continuously

That was my first idea, the pvc just seemed a little easier to do explain then I could just ask about flush valve

prediction: green pvc drain clogs with roots, overflows top bucket, and ruins your floor. water pump burns out from lack of water and then roots die from lack of O2.

What about like a toilet, kinda, like instead of chain on handle it’s on float So when it fills it auto drains and use a dome screen in bottom to prevent clogging hole

Just get a single 17 or 27 gallon tote and put a small 150-200 gph pump on it and pump out the bottom and right back in the top to create a waterfall.
If you do that right you don't need airstones.

This is a self contained "waterfall" box. I went a bit further and made something similar to a cloner spray bar and mounted it at the top spraying down. i gave it a drain valve and hose connection so i can hook up the hose to that end and turn the valve and it pumps itself out. You could get away with something as simple as just a 90 degree elbow dumping back into the box.
