It is usually accepted by coilers that 3-coil systems can

It has been confirmed in the case of energy conversion systems, operating in a low mode as 1:2:3. For a system operating in a high mode, it is really not clear if an advantage exists. Maybe a somewhat
faster (less cycles) energy transfer.
There are other factors and possibilities.  For example,
splitting the resonator into a secondary and tertiary and
applying strong coupling to the secondary will produce a lot
more overtone content - for geometrical reasons.   Do these HF
components contribute to streamer channel heating?   Hotter,
brighter breakout would be a general result, not requiring
specific tuning of the overtones.
This is something that I suspect that may have some effect. What would be the effect of "shaking" the charge on a developing streamer with the higher-frequency electric field from the overtones?

There is also the question of what happens in a magnifier after the quenching of the spark gap. The secondary voltage is not the smooth decaying sinusoid of a Tesla coil. It has two tones, not one, and the voltage over the "transmission line" may rise above the limit during the energy transfer transient.
