I think I might have found a cheat out of this; connection in series.

I could use short cables from the main panel (sits behind the center monitor) to the left and right panels on each side. Then thick power traces along the PCBs, short cables out the other end to the next panels on either side of the user (the panels wrap around the user, like an airplane cockpit).

The trick seems to be external cables as short as possible.
