I happened to think this weekend about setting up my Mark III with
parallel lenses rather than staggered, just to get a little better
relative photometry and a little more observing run time. The downside
is that seperating the lens views gets rid of some slow-moving objects
like satellites (or reduces them to mono-colored objects). Maybe
a pair that is stereo and one offset could do both...?

As for your kilometer-wide pair, you've got a site in Cincinnati OH and
one in Dayton OH....? Can you ask those guys if they have some same-night
observations? It's likely, they have the same weather pattterns to first
order.  That's a 50-mile baseline, but even less as Dayton is northeast
of Cincinnati (the latter is my birthplace).
