The new design widened the bottom cushions to 27-1/2" on each side. This resulted in a 14" or so wide aisle. This was based on lots of reading on this and the Sprinter sites about bed width and trying, somewhat unsuccessfully, on manufacturer sites to confirm a useful width. It seems slumber is in the closed eye of the slumberer. The challenge was to make the beds as wide as possible while leaving the aisle wide enough for crosswise feet while sitting.
We wanted the option for smooshing the cushions together to as well and that meant support over the center aisle was needed for those times. The Lagun table tops (2) were cut to the needed width, and one additional piece will fill the center. It turns out we both sleep better with the added space that magically appears when the cushions are combined instead of being separate even though the total width doesn't change. When the cushions are combined, the two cushions over the rear of the center aisle as used as blocks outside the cushions to hold them together.
We eliminated the boxes around the GWV window shades so the side walls were smoother and nicer to lean against. The blue cushions you will see in the photos we use as backrests against the side walls and the two center aisle cushions we sometimes use as back rests against the rear doors. When we do that we place the cushion side against the door and then the blue cushion against that. It has turned out surprisingly comfortable. Not as much as the recliner beds as others have, but that may be a future project.
The bottom end of the passenger side bed was lengthened by 3" and an inch perhaps on the rear end by closing up the space to the rear doors.
This is what it looks like now:

Despite my partner's infatuation with the retracting center table in the original it just did not fit well with the expansion of the closet hanging over the foot of the driver side bed. We squared it off as Avanti asked GWV to do. That extra space would have made getting in and out of the driver side seating, so we went with the Lagun table which has worked well when combined with the two center aisle cushions, the fixed side of the the top being used as extra table space. We have a base for an additional Lagun table to be installed near the foot of the passenger side bed, but have never used it. This paragraph is what I meant in the initial posting when I said everything effects everything else.
