Exactly what I did, more or less (no spot on LX).
The simplified Cave zone system sez expose normally and develop for mild negative if you had high contrast scenes.
Problem is that when you push to 1600 or more it's difficult to both push and get mild contrast.
So there's no Ansel thing in that.

Or, to paraphrase, spot-meter on the skin tone, then apply perhaps minus one stop or so of exposure compensation?
I don't see where this requires knowledge of any Zone system ...
