PS6 content fill aware tool

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 but anyone who's been to this place will know it's kindy scary at the edge!
