A 4 pack MOT power supply does NOT need any transformer modifications if you 
run the middle MOT's grounded. Oil will be needed most likely to cool off 
the transformer bank and provide protection against RF feedback. In effect 
you create two seperate transformer curcuits which operate independantly at 
4800 VAC or so. MOT cores are built to survive up to 6 kV before insulation 
failer. Only past 6 kV do you need to do modifications.

An 8 pack power supply is very much possiable, but some MAJOR transformer 
modications need to be made in order for it to work successfully....it takes 
at least 8 hours to modify the secondaries/ add Varathane/ pull out filiment 
windings on 4 transformers
(2 left, 2 right side)  I would stick with 6 pack supply which is 100% fail 
safe and only needs 2 modified transformers (1 left, 1 right side), but high 
quality transformer oil must be used!
