Oxygenating through a corny

Anyone hooked a oxygen tank to the gas in post of a corny to aerate wort?
Looking to moving to all corny fermentatin this is one method I'd like to incorporate into my system

I was thinking about using a Corny as a bright tank/oxygenation tank, installing a dip tube with a carbonation stone attached.

Thinking around the same lines. Could you fit a stone through the post holes? otherwise you'd have to put the diptube in and then add the stone to the end of it.
I was thinking just fill the air space above the beer with oxygen and giving the keg a shake, but only because i couldn't think of a good way to fit a aeration stone in while keeping the keg sealed. I've never had a stone in my hand so i don't know how big they are.

I believe williams brewing sells something like this
