Well, my curiosity got the best of me and I had to experiment on Sunday. I mixed up some soybeans, sunflower, buckwheat, trophy rape, forage radish and winter rye. I used a round style corn plate, just slightly larger than the soybean seed, which was the largest seed in the mix. It worked like a charm. It dispersed the seeds in a random fashion. From my calculations, it would put down around 56 lbs. per acre. I will have to work with the seed mix a bit, or just purchase a premix type for my planting needs. I should probably include some annual clover, but those seeds are even smaller than the rape seeds.
