one suggestion ...
Instead of storing 4 X 8's on the panel saw side, create a vertical space behind it about 6" wide to store them. My panel saw is also on large casters for rear access so that I store lumber on the back side.
Maybe your saying the same thing, now that I review your drawings. The big advantage of a panels saw is not needing 20 ft of run for ripping IF your saw carriage moves horizontally... I donno, but I don't think yours does. I designed mine after many hours of engineering so it does hang from a rail at the top and will slide a total of 9 ft. end to end, no easy task.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
