W,

Yes, that will work.  I once tried 4 MOT's in series, this drew 6000 VA
and gave 63" sparks.  The two "outboard" MOT's were "floating"
electrically at 2000V.  When I added some external inductive ballasting 
to the input, the VA draw was reduced to 4000 VA, and the spark length 
remained the same.  The tank capacitance was about .072uF or so.
I used a rotary gap running at about 550 bps.
