Some abbreviation I'm not familiar with for Monsignor? I'm
pretty sure I've not been called to the RC priesthood, or for
that matter the RC church in general. I prefer Sagamore or
Trismegistus if you wish to give me an honorific.

There's nothing currently available to do this. Nor am I enthusiastic
about the prospect of anything that doesn't break some essential
aspect of Tor working. (I don't mean implementation. I mean it will
fail on an abstract protocol level even before that.) At best you
might reduce this from virtual certainty to a very serviceable stochastic
But that's a good thing, because otherwise Tor would be more vulnerable
to long path attacks.
