The GM waste fire coils may be the ideal candidate.  Potentially it could
still fire two plugs.  Depending on how the 80v/400v source is generated,
it might be simple and inexpensive to generate an additional bias voltage
of the opposite polarity which would allow this arrangement to work.  But,
what about the rest of the circuit?

Alot of maybes here.  You've expressed some displeasure with the
naysayers, but perhaps if we had more info there would be more
constructive feedback.  Post more details.

There's a good reason the high voltage post on the coil is so well
protected and insulated.  In the quest for a four terminal coil, what do
you expect the fourth terminal to look like given it's on the other side
of the high voltage winding?  It might have to be just as well insulated
as the post going to the distributor/plugs -- it might look just like a GM
waste fire coil.
