With a no-till drill, I got a similar effect, but less corn by mixing corn and beans in the seed bin at a 1:7 ratio by weight. I was including the corn for structure in the beans, rather than winter carbs since I'm far enough south that summer is the primary stress period. This density allowed sufficient room for broadcasting WR/CC/PTT mix for fall after the beans yellowed. With that light mix of corn, I was able to get cobs without adding additional N.
I think if I were up north and wanted corn for winter stress, I'd go with your method.
Thanks,
Jack
