Long story short, Thyratron tubes have been tried without a lot of
success. They are much happier switching DC than AC, and do not survive
for long with large reverse currents.
I think it was Richard Hull who built a small tabletop unit with a
hydrogen thyratron, but is was in the one MOT power input range, not
pole pig territory.
Thyratrons are like SCRs -- once triggered on, they stay on till the
forward current drops to a specific level. In a spark gap system, you
have bidirectional AC current passing through the gap, not something
that fits well with the thyratron mode.
