It’s impossible. It takes 39” in both directions to even begin to have something useful. And it wastes a huge amount of space for the pie shaped inaccessible pieces. A super susan proves more square inches of storage and is just as accessible. It needs 36” in both directions. You may need a void corner.

You need a better KD.

I was going to do a fancy pull out corner cabinet for my kitchen, but then the designer actually persuaded me to leave it simple, just normal shelves. I really loved the suggestion, because it’s now the best place for all my bulky pots and pans and maximized the space over using pull outs or susans

I agree with sunshine. That big open space of bottom and one more shelf is great for larger items not used as oten.

The drawer boxes would need to be shallower, front-to-back, and I'm not sure how the glides would work. I think it would be only ap 18" deep from the front inside corner to the back of the box. Cpartist has corner drawers and loves them--maybe she'll weigh in later. 1 square = 3", diagonal of 12" square is ap 17":

Can you make the cabinet next to the corner wider?

Something like this might also work on the 17” side:

And then a straight pull-out on the 12” side:
