Neon EXFRMR power rating

Hello, I am wondering if it is possible to increase (safely, well, 
relativly) the secondary current of a Neon transformer by placing 
capacitance in parallel with the primary? I have a neon with plate 
ratings of Secondary 120 mA -at- 15000 V, but a 120 V -at- 1000 VA primary, so 
is it possible to improve the power factor of this type of transformer?
And what would the formula be?
