I've given quite a bit of thought to this problem...

Certainly, for the SSTC type drivers or VTTC coils, which are basically
power oscillators or amplifiers, it would be trivial.

For a spark gap coil, though, it would be a bit trickier.  I suspect that
one could find some interesting arrangement of Primary L and Primary C and
interconnections (possibly with two primary windings on each coil?)  that
could be adjusted to produce 120 degree phase shift around the ring.  One
would have to deal with the significant change in load impedance when
streamers develop, especially asymmetrically (or, maybe not... most spark
TCs are fairly loosely coupled, so the primary might dominate).

Transmission lines would have to be impractically long. I think you'd want
some sort of adjustable L or C in the primary tank.

You also have the question of using one or three spark gaps, and whether DC
operation might useful.

Another idea I had was to use triggered spark gaps, and very carefully
control the timing among the three gaps (to fractions of a microsecond,
probably.
