FWIW I like this plan much better from a FMEA point of view.  Worst case if
there are problems with the flywheel drilling project, you could be looking
at junking the flywheel and there you are dropping the tranny anyway. And
with all respect to the fact that someone has done it before, drilling
in-situ through the hardened pin, getting location exactly right, all just
sounds like a mess with multiple ways to have things go wrong.

Drilling the bellhousing for a new sensor location on the other hand has far
lower 'worst case' implications. Mounting doesn't work out or it's wrong
spot, meh you've got another small hole in your bellhousing. Fill it with
some of that extra epoxy you've got lying around.  Other thing that occurs
to me if doing this option would be to fab a mount for the sensor that
allows depth adjustment to get that critical spacing you talked about
correct. Use locktite and a locknut to affix it once you've got it perfect.

All that said, I've learned the painful way that often it's far better to
suck up taking more things apart and out of the way than screw around for
hours/days with a work around to avoid doing it.

Are you sure all this isn't more trouble than just dropping that tranny one
more time and getting it all back together the "right" way forever?
