Hiya Lon,
Glad you're enjoying your system. I'm jealous of your new TV.
Personally, I would hesitate to put the speakers that close to the corner of the room. If I understand you correctly, they would be very close to the side walls. When I had my system in a different room with the right speaker in a corner, the imaging got pretty wonky.
As an alternative to the two towers, perhaps you could get a bench with room for components underneath the TV. Here is an old crappy picture showing my monolith RPCRT with button-boxes below it.
As far as the sub goes, rearrange a bit and find someplace else for it in the room. Positioning at the front of the room is not at all critical, IMO. My SVS is an end table.
My final advice is to give your lovely wife whatever she wants. Happy wife, happy life.
