Jim - good question.  I tried using two triggered spark gaps, but I couldn't
find a way to keep them from firing at the same time--with disastrous
results--even though the triggers were alternating with lots of dead time
between the triggers.  So I gave up & used the dual-gap RSG solution.

And yes, for either configuration, filtering the DC power supply is a good
idea.  I used 24 Microwave oven caps in series-parallel to get the ripple
down to less than 10%.

I wonder if you could make a triggered gap version of this?
