Yes you can remove any number of magnets. And yes, it's common on 12 bolts, Dana's and 9" Fords with stock yokes to open up the hole to some unusual size/shape.  It's not a crankshaft - if you keep it within .050 of straight/round, your sensor will see the magnet.

Magnets are oriented South side out (required to work on Racepak, MSI and most other hall effect sensors)
