Scot,

I'm not sure what you mean by the system?  The combo of
the series pigs?  You are correct about the ~30kV resulting voltage.
Each pig will still see only ~15kV each with the center point of the
series pig's secondaries grounded.  It's the same as putting two 
MOT's in series and grounding the cores.  As far as the rest of
the system handling 30kV, I've recently done tests on my small
research coil (TT-42 type) with 42kV peak on the primary.  Higher
primary voltage is good because it lets you use a more primary
turns for a given bang size (smaller cap value), and improves the
surge impedance and reduces the gap losses.
