I have been working on this very thing. I have (3) 1200 volt SCR's rated at 90 amps that I am attempting to use in series to trigger a low voltage coil. Well, low voltage for a TC, anyway. Steve Ward recommended a way to simultaneously trigger all three SCR's and I am working on this. I haven't made much progress, yet, because I sold my O-scope and bought a new one to replace it that I only got in very recently.
I'll be glad to share what I am doing, if you would like to write to me off list. If it is okay, I guess I could share what I am doing on the list. It is on topic.

Hello all, I'm having difficulty getting my stationary spark gap to work properly. Iam wondering; is it possible to use an optocoupler (triggered by a 555 timer or maybe a function generator) to trigger a pair of massive SCRs to imitatethe function of a spark gap?The biggest SCRs I've seen can handle 1kv (probably rated in DC, but i'm notsure), so it couldn't be too big of a coil. I'm just wondering if this would work or if I'm missing something obvious.
