Mike, all,

In the past, I've wired 4 MOT's with secondaries in series and obtained
64" sparks.  Some corona-sparkling could be seen between the core
and winding on the "outboard" MOT's however, but they held.  The 
system used a non-sync rotary gap, and a .08uF cap.  Without ballasting,
the TC drew about 6kVA.  With ballasting, this was cut back to about
4kVA, spark lengths were the same in either case.
