Content aware fill tool PS6

Is the content fill aware tool in ps6 smart enough to remove the rocks in the foreground so that I can have a full view of the river around the bend? I would have to use a friend's computer since I don't have the software myself, so would like to know how challenging it will be before I give it a try.

And I could kick myself for not having been daring enough to go right up to the edge for the photo to avoid all this photoshopping altogether emoticon - sad but anyone who's been to this place will know it's kindy scary at the edge!

Posting this here coz I got no responses in the retouching forum.
