I have been looking at the photos.
With the 96" of the 4 x 8's perpendicular to the long wall, spaced 21" off of the wall, I get a 21" space between the support poles and the table.
If you move 21"- 24" off the door end wall, what is left to the end where you knocked out the small wall? Is that the 16' total length or do you have walk space on that end?
I am trying to float the 4-4' x 8' and then extend the width through the knocked out wall with the 4' x 4' table.
That would need 192" +21" +21" for walkaround area.
I moved the crossovers to the curves, 1 on each end to clean up the center.
As you can see, that configuration creates some nice area. The other thought that I had, was to put the 4' x 4' in the center between to poles.
Sorry to bug you, but the photos weren't contiguous. I couldn't count blocks on the long wall.
