I tried two sets of pole pieces and pickups early on in the CBS wheel test bed set, 48 red field and 144 all field pulses.
The only immediate change was the fairly loud 144 Hz whirring sound as the pole pieces passed the pickup!
I think it would have worked except I blundered the 144 pickup and shattered the disk edge where the 6 pole pieces had been.
There are still more schemes to try as soon as I get time.
