how about one or two central stations in the middle
think of kitchen islands
if you can find some used kitchen base cabinets for cheap-cheap use those for the base
now you have storage options for less used items (cutter, vinyl, t-shirts, etc.),
but they are easily lifted into place when needed
even though it utilizes the same width, there are far more options than two thin top surfaces
you may even find you have enough room on the edges to add a foot or so of surface,
and still be able to walk/work around easily
