Upside-down magnifier

Dear List,
Referring to the transformerless TC-capacitive transformer TC hybrid, is 
this not an "inverted" magnifier -in other words an ordinary magnifier 
turned upside-down ie. the extra is connected between ground terminal of 
the "secondary" (composed of L1 & L2 in series) and the top terminal 
instead of the normal arrangement where the extra is connected between the 
HV terminal of the secondary and the toroid.

Thus the HV-energised ring in the TTC-CTTC hybrid is equivalent of the 
ground plane in a normal magnifier.

Also, doesn't the combination of the extra coil and topload capacitance to 
the opposite terminal  basically constitute a series resonant tuned circuit
with the current drawn by the low-impedance "input" at resonance limited 
solely by the dynamic impedance of circuit -predominantly the resistance of 
the coil?

Therefore, wouldn't the best way of exciting the series resonant circuit in 
theory be via a high-current, high voltage signal generator without any 
transformer between the output stage and the tuned circuit to cause 
addition complexity?

Also, on the subject of "inverted" magnifiers and other less-conventional 
designs -which I am interested in- has much work been done in this field?
