Yes, that would be in the "signature" tooth family, with one tooth or gap longer or shorter than the rest. It might be possible for @noisymime to write the equivalent of an 8+1 decoder for it. As all the images in your linked thread are missing, we would need to verify the timing of the leading edges are actually even. You could also confirm that with dividers or protractor to measure the leading and trailing edges fo the holes and relief. Otherwise, there are many trigger systems using signature sync, and it's on @noisymime's to-do list for creating a more universal solution for all these various versions of it.
Alternatives in the meantime are filling one hole (create a 'missing' tooth), or add 7 more holes (16-1), or add a rev sensor (such as the edge notch at about 9 o'clock in the photo, or keyway, or bolt/screw head, or crank counterweight, etc.), or add some form of cycle sensor on a 2:1 reduction gear, timing gear, cam, rocker arm, intake valve, etc. A missing-tooth or rev sensor would allow batch and wasted-spark, while a cycle sensor would allow independent cylinder fuel and spark, if that matters to you.
