OK, two people agree on the strings to use, but what are the semantics?
What sentence would go in the wiki to describe a) when to use the value
and b) what the value implies once it is in the OSM data? 

It sounds like it might be something like: 

base: the end station with the lower altitude 
head: the end station with the higher altitude 
mid: any station, not being a base or a head station, irrespective of
the altitude 

note: based purely on altitude, not arrival/departure inclination 
  That sounds perfectly reasoneable to me!

> As to which key to use, how about aerialway:station={base,mid,head}?
 I suggested station={base,mid,head} because we're using aerial=station
and then it seemed natural to go with station=* but I'd be definitely
happy with aerialway:station=*.

I suggested aerialway:station=* precisely to avoid overloading station=*
(different semantics under different circumstances). 

As a native English speaker by the way I would suggest that "top" and
"bottom" might be simpler instead of "base" and "head". Using easy words
means you don't need to explain it to people who either don't know the
words, or know them in a different context.
