I remember reading a message that said that two transformers must be "in phase" before the current will double. If they have the same line level input, then won't this be automatic? (the two transformers are identical brand/condition/etc).

Would be the proper setup.

The above could pose some minor problems in the flow of electricity.

Yes. NST's have power limiting built in.

Assuming that the 15kV's are 30mA and the Pole Mount is 5 KVA -at- ~15kV
(pulls out calculator)
~11 NST's given the above specs and assuming that you aren't overloading
the xfmrs

You have my agreement there
