The premise of that other one reminds me a little of Marvel's Damage Control. Only instead of cleaning up after super-battles, it's cleaning up after kaiju with an emphasis on disposing of kaiju bodies.
They both sound like fun. I know there are probably some kaiju purists out there who hate these concepts. But I'm the guy who came in and suggested a starry-eyed shojo comic where the heroine turns into a kaiju, so I'm certainly no purist.
