There are other, more efficient ways to increase the surface area -
especially the ratio of surface area to volume, to mass of plasma, or to
number of neutrons, all of which ratios go down if you go big.
(Volume/mass/molar count at given density scale with the cube of linear
dimension, while surface area only scales with the square.)

Or did you mean to decrease the surface area's ratio?

Also, is there a discrete surface?  My impression was that plasmas don't
have surface tension the way liquids do.
