sounds like a standard wasted spark EDIS setup, but with individual coils. I see no reason why you can't connect two of the coils up in parrallel, have a look at this wiring diagram from
mpickett (a pelican member)
who has the dual plug Megasquirt EDIS setup. You may want to PM him.
The reason I keep refering to dual plug setups is that firing the wasted spark is like firing the dual plug spark.
