Well, I hate to burst your bubble but I think that two twin systems
together would work about the best for your proposed setup. Ie four
secondary coils A, B, C and D, with A and B being 180 degrees out of
phase and C and D being 180 degrees out of phase. Line AB would be the
perpendicular bisector to line CD. Quite a while ago there was talk of a
6 coil 3-phase 3-bipolar setup (noone ever made it to my knowledge
though) which would share a common rotary gap and fire the coils in
order going around the circle creating a rotating spark mass. Sounds
hard to picture but if you think about it...

Then there is the topic of creating a delta or wye shaped spark with a
"tripolar" three phase coil that comes up every so often on the list.
