I have a theoretical study:
http://www.coe.ufrj.br/~acmq/tesla/magnifier.html
And have made a magnifier, that worked as expected at low power, but had 
insulation problems at
high power:

I still don't have a design procedure for a system where the three coils 
are magnetically coupled,
although surely there are solutions. The modeling of the distributed 
capacitances of the coils would be
complicated.
