On one hand, you're not crazy, but OTOH, people will choose one or the other with the given circumstances.
I think bluray has completely changed the HT game. Anything from being able to supersize image with a +600% increase in resolution, to lossless mch tracks for demanding classical music concerts.
Look at the deals section where j garcia posted the pana player + 3 BDs for $140. If you're considering BW803s, then IMO it's a drop in the bucket for the capabilities you gain.
The big elephant in your room is acoustics/setup. If you only have one foot behind you from rears, I might assume that you are simply sitting too close to the back wall. If you must sit that close, you are advised to heavily treat it with broadband absorbers. If you sit that close, many might say to lose them, as well.
Also, your square dimensions puts you at an upward battle.
I agree with you that 90% of TV doesn't really benefit from mch.
Really, you'll have to see for YOURSELF how any speakers will sound in there, to your ears. Rooms can sound sooooooooo differently, it's pretty much impossible to "talk" out a solution. And remember, over half of what you hear is the room.
Please keep your mind as open as possible in regards to both speaker placements and listener placements.
If seating is very centralized, or even just for one person, the higher the changes that a phantom/stereo setup will be the right ticket. And IMO the higher end BW can image like nuts. I've shared a story on a few occasions of suspecting that the center speaker was active, when it wasn't, in a very good demo room.
