Displacement is definitely not going to work. There is a couple of grass areas that range from 10" for one, and a foot and a half for the other. Right now I am working with a combination of proxies and comping in real grass in post to clean up the edges.
If I can get something like the second image on the linked site below, it might look quite nice. But I don't want to extreme render times. I am fine with it taking longer, but if it more than doubles the time required for the high res image, I am going to use something else. Right now I am at about 1-1.5 hours for a 4000x4000 wide image.
