I was looking over Alan's article on Dolby's recommended speaker positioning and came up with the following for my room:

The shaded areas represent the speakers' direct radiated sound to what I guess would be considered the "sweet spot".

Does this make sense or do you think I would be better off with W2s at the back of the room? If located at the back of the room they would have to be closer together. I thought that this might yield better imaging.

Room area specs: Area: 267 sq.ft. (Volume: 1779 cu.ft. - yes I know, low ceiling, but we like to watch our movies sitting down), Length: 22'-8", Width: 11'-11"

Reason for my question is I am mounting the speaker terminal boxes in the walls and running the inwall speaker wire (currently only outside walls are constructed, no interior partitions yet). Worst case scenario is that I run two extra speaker plates at the back of the room anyway but I think an extra set of unused speaker terminal plates would be a waste of materials.
