DIY return pump shut off switch - is this crazy?

I am thinking of adding a shutoff switch to my return pump after a minor flood. <Got a new pump, didn't get the overflow set right ....>

From looking at the web, it seems I can spend $100 to buy a shut off unit, or a complicated build using relays, etc.

I had a simple idea ... Suppose I wire the float switch to the Neutral & Ground of a GFI plug. <Neutual & Ground because there is no Volts between those wires.> With the switch open, the GFI will work normal, but it should trip when the switch closes. Basically, I am using the GFI circuitry as my relay.

Do you guys think that this is a good idea? Or am I totally off my rockers?

So basically you want to setup a reverse ATO? The float switch is underwater and the circuit is opened, but if the water level drops and the switch becomes exposed, it cuts the circuit.
I never heard of anyone setting something up like that, but I guess it would work.
