The lower voltage NST's that you mention, while not as desirable as a
12-15KV unit, will certainly work. The 2.9KV unit sounds suspiciously low
for an NST though. While there will no doubt be some that would disagree
with this, I believe that you could parallel the outputs on the 5KV and
7.5KV units to realize a higher-powered power supply than either unit alone,
despite their dissimilar voltage ratings. Just make sure the 120V side is
phased correctly.
You didn't mention what current rating your units were so I'll assume that
they are all of the lower powered 30mA-and-under variety. With this amount
of power, the 4" PVC tube is probably the better choice.
