How feasible is this with today's technology if the output media is
35mm film, and a constraint is no more loss of image quality than would
occur with a film-to-film dupe?

I can see where the fix would be fairly easy in the case Bob describes, and
probably also in the case of the two people moving at different rates
of speed across the ground.  But what about the waves lapping at the
shore of the island in the picture of the Statue of Liberty?  What
sort of techniques would be applied there?  Copy the waves from one
image to the other and ignore any perspective shift because they are
so distant?  What about something not so distant that is mismatched?
Does this then get into the sort of painstaking work done by Lincoln
Kamm and others...manually modifying the copied part of the image to
simulate the proper perspective shift?
