The shot plot you mention should be planted in the fall, around here we will be planting the same thing at the end of July. I wouldn't plant long season brassica's, I don't think that it would be worth the trouble when you can just plant them in the fall. One thing about the brassica's is that when you get the first hard frost the sugar content in them goes up making them more attractive and thats when the deer normally hammer them.
You said you had a acre of beans, did they wipe out the field or did it survive?
Around here unless you have 3 acre's or more it's hard to get soybeans established.
If you can get beans planted and they come up without the deer wiping them out along with shot plot I think you'll do well.
Don't know what you all are aware of but beans should be planted in the spring at about 1" and you should but some inoculate on the seed before planting so that they can fix their own nitrogen.
Shot plot I would plant in the end of July and no deeper than 1/4".
