How tall are you looking for?
For what your asking, I don't think I'd go with a NWSG - it can take up to three years before they become established. Cool season grasses may be a better bet as you will get earlier greenup in the Spring and I think they establish easier and more quickly.
Have you thought about just a plain old Brome grass. Or maybe Orchard grass mixed with a red and white clover. Orchard grass for some height, and the clover for food and to help shade out other grasses and weeds. Maybe toss in some Little Bluestem and Bluegramma as a warm season grass to the mix just for fun.
A range quality Buffalo grass would be a good choice if you wanted to go the NWSG route, but I don't think it will get the height you will need to make wildlife feel secure, at least deer anyway.
Sorry I can't be of more help.
