They key here is "parallel". Voltages don't add up when their sources are
not connected in series. Because of grounding issues and the fact that neon
sign transformers are center tap grounded, you cannot connect them in series
to get a higher voltage.
Connecting two power supplies together in parallel will provide a higher
current than either of the transformer alone. In this case two 15kV 30mA
transformers together can provide 15kV at 60mA or the total current of both
to obtain 30kV at 60mA you'd at least need four 15kV 30mA transformers- two
in series and two sets of two in series in parallel. As mentioned above, you
cannot do that with neon sign transformers though- so this does not work in
