I don't know what kind of current you're going to be needing, but 
microwave transformers probably won't need to be paralleled for higher 
current, and you will need current limiting to use them.  I was going to 
wire four 4kV units up a few years ago as two paralleled sets of series 
connected units.  After I wired two up in series for 8kV, I decided to see 
what just the one pair would do.  When I was drawing an arc, they were 
pulling about 70A from the wall!  Needless to say, my 20A breaker 
didn't take that for long.
