Paul, 

As long as you remember to short the secondary on each 
of the MOTs, it will work. I'm not sure why you would want 
to have the option to choke the pig's input thru as many 
as 4 seriesed MOTs. I would to just opt for the SW3 thru 
SW5 / MOT configuration for pig ballasting. You are on 
the right track, though :-)
