Worth a try. At some point the limiting factor will be the internal
insulation between the primary and secondary.

Might be possible to build multiple isolated driver circuits and
synchronize them via opto connection....

As an empirical datapoint...
Some years ago I had a car that repeatedly burned out coils. Put on a new
coil, it runs fine, a couple hours to a couple days later it would be back
to no spark and a new coil would put it right again.
After more than a little troubleshooting, it was discovered that the
ignition pickup coil (sensor) was malfunctioning and causing "extra" sparks
when the rotor in the distributor was not pointed near one of the
terminals. With nowhere to go, the voltage would build up until it found an
insulation weak spot inside the coil and flash-over. After enough of those,
you end up with a nice conductive carbon path inside and no more sparks
outside.
Moral of the story - the internal insulation will fail at some point.

P.S. I'm a big supporter of the "_DO_ try this at home" concept. So, yeah,
try this, but please be careful. I would like to hear what the results are
from you, not your next of kin. :-)
