Sounds like what Honda has been doing for years.  The high voltage 
lead is not grounded in the coil at all, the current path is spark
plug to coil to the other spark plug.  I've also heard that the 
scavanging spark helps emissions slightly.  A very big side benefit is 
that by using separate coils, the effective dwell, and consequently 
the amplitude of the spark, is increased.  My motorcycle can run
through a furious cloudburst and not sputter, although I do.
