You wouldn't be able to selectively toggle between case-sensitive and
-insensitive searching this way, though, so I'm not sure if there is
merit in doing both cases in the same position or not.

Not really. Terms in the index are ordered
lexicographically, including case. It certainly would be
possible to write customized Query subclasses to do this sort
of thing at the expense of performance.
The only techniques I'm aware of are to either build separate
indexes or index the same information into separate fields of
the same documents using different analyzers per field.
