Sure, use the two-SCR circuit, the one where they're coupled with a capacitor so one turning on pulls the other off. The spark gaps must be somehow rated for continuous discharge (arcing) and exact design (minimum holding current, voltage drop) depends on gas pressure and composition. And probably electrode material and condition (hot electrodes ignite easier, thermionic emission).
Given how unreliable spark gaps are, good luck on getting consistent operation out of it, I suppose. But it should function, when it does.
A single spark gap also functions as a bit storage, if given a fixed voltage (with current limiting) below the breakdown voltage but above the arc voltage. It will be bistable: once extinguished, it remains off; once ignited (say by mechanical contact, or a small trigger arc to one of the electrodes), it remains on.
A direct application of this, in two ways, is a welder: One, obviously, when the electrode is at great distance from the work, nothing happens; when ignited, it keeps going, etc. Two, when HF start is employed, it functions the same as applying a large AC bias to any other hysteretic system -- like the AC bias used for recording audio tapes, which overcomes magnetic hysteresis. In this case, a high voltage overcomes the arc's hysteresis, making it much easier to use -- no striking needed.
