I have no experience with multi-cylinder R.C. airplane engines, so this is in the form of a question, not given as a solution to the claimed glow twin dropped cylinder problum. If the O.S. twins are truly "prone" to lose a cylinder in flight, and I don't know that to be correct, why wouldn't an on board glow igniter system such as the Sullivan system relight the flamed out cylinder by reducing the throttle down to the lower range where the system would be set to turn on the igniter. This of course would assume that both the glow plugs are good. If you have a bad glow plug in one cylinder of a glow twin, that would be no different than a bad spark plug in a twin gas engine. You need to have good "plugs" in any engine, gas, glow, twin, or single cylinder. With one cylinder still running and turning the engine over on a twin, I would think relighting the out cylinder would be possible. Or dosen't it work this way?????
