Hi Darth Racer,
Yeah, that's one of the pics that I forgot to take and post here, but I will...
This is the plate I bought off ebay, $40 delivered.

I didn't use any of the mounting hardware that came with the plate because I just welded it to the frame underneath. So far my welding has held up, I've beat it hard pushing QP gravel & now the snow. I have about 200 feet of driveway and a large lot area to plow.
I *really* like your idea of a dumping bucket. It could be something simple with a trap door bottom, hinged in the back that is worked by another electric winch. You would definitely have to beef up the front end of the Rhino to lift the added weight because as you can see in my video, the front end squats when I lift my plow.
Here's another video of my setup;
