a good amount of coasters end up setting on land that's topo. doesn't look like what it did when it's project started. look at Diamondback for example, or even Firehawk.
anyway, the land to start out with looks much closer, imo, to the computer animation at the big bad wolf site, but i have been wrong many, many times before and with saying that, i'm not going to rule out what your ideas are, especially since nothing has been released other than the computer model.
as for the myth busted comment earlier, that was me trying to be humorous, but i guess it didn't work, but i still believe that the bbw site is a closer match than Son of Beast's
*i've also noticed that terpy hasn't been commenting anymore in this thread, i think that one of the two of us is on the right track.
