You might be able to use a coil on plug solution, which sometimes have the igniter on-board. The GM used on LT1 V8s, I believe, have igniter built-into the coil, and these have a short spark plug wire. If your coil is near the exhaust, the short wires will help to keep the heat way. Another source are coils from late model motorcycles.

Any way you go, it won't be cheap, but if you have a twin-plug engine, you probably aren't a pauper.
