Take a look at GIK Acoustics Tri-traps or Real Traps "stands". Either of these may be both the ticket to WAF aesthetics and broadband absorption....frankly I don't like the awkward look of 4 inch panels straddling the corners either.
See my virtual system components for pictures of the GIK Tri-traps...you can order them in eight different colors. You need to purchase about 16 linear feet to make a modest improvement, as treating only one corner is unlikely to make an audible difference. I was in two minds whether to get these or Ethan's stand traps - no doubt they both work effectively if you get enough of them.
