I can see where the B&W 805D3s would be a good pairing for the same reason the Focal would be — higher impedance, front ported, and a treble that can be a little bright and tamed by tubes. From what I have read, the B&Ws still benefit from being pulled out into the room 2-3 feet for proper imaging.
One bookshelf you might consider is the Aerial 5T (4K new). It is front ported and was designed to be placed within 2 inches of the wall. It has specs very similar to the Sonnetto, and definitely is tipped to the yin, so my previous concerns apply here as well.
