Who can say? I think if I was going to try it I would put it between the end of the coil and the collector first. With the diode off the end of it. Its an interesting approach thats for sure. I think you should study Tesla patent 568177. His unusual approach to powering this device has some clever insights into how chokes may be used. Use a cap on the secondary instead of the ozone plates.

You should build a stock sg (single coil) for your tests so you can finely tune the parameters and study its effects.
