If I may be so bold, I have been thinking that instead
of using switching devices to vary currents and
voltages as we presently do, how about
changing say, the capacitance instead -charging at low
voltage and discharging at high since charge ,Q,  on
an isolated capacitor doesn't change with a change
in capacitance but stored energy and voltage do vary
with changes in the capacitance.

Would this not detune your coil thereby losing the
resonance(or maybe this would improve quenching)?
Tesla studied the effect of charging a cap of two to
four times the tank cap's size and letting the spark
gap switch the energy into the tank circuit.  I don't
know what effect that has on the output, because the
tank circuit would never be quenched, but since he was
trying to develop a transmitter, this might lower the
output to suppress the arcs and have a longer ringdown
time for the output waveform - making it more like a
continuous wave output.
