I've tried that. All else equal space winding kills inductance and
performance (lost nearly half my spark length even though they were bright
at .385 coupling. I'm guessing having a bigger secondary to make up for lost
inductance would work, but probably wouldn't look all that impressive with a
giant secondary giving off less-than-giant sparks.
