Other than trading in the sextant for a barometer or GPS?
You need an external, known-height reference. The easiest process I can
come up with is to be sitting on a height with an artificial horizon and
a sea-level horizon in view. One could measure the dip and work back
from that.
Not very accurate I should think.

You wouldn't necessarily need the artificial horizon.
