Precisely. I could not have said it better myself. Three phases,
three stationary electrodes on the gap, three capacitors (one
charged on each phase), exciting a single primary coil.

Cha-ching! (Sound of the cash register opening in my head...)

Tesla has this pretty well documented in the publication I
referenced the other day (~Tesla on Alternating Currents~), even
to the point of describing in fair detail how he ran up to eight
phases with alternating current generators into his tank
circuits. In a separate section of text he described (and
submitted photos of) a powerful multi-phase alternator that he
used. He specified that he could step up the output voltage of
the alternator with a custom transformer set and I quote: 

"commutate them by a commutator consisting of aluminum plates, or
aluminum segments, which were rotated in synchronism with the
alternator. Then I obtained a continuous pressure; that is,
direct current of a tension of 44,000 volts, and with these
44,000 volts I charged my condensers."

This is exactly what I mean and it does sound like fun.
