Would space-time get "stretched thin" between two (large?) black holes?

... and if so, would there be anything special about "low-density space"? (The thought came to me when thinking about virtual particles in extreme vacuums)

I don't think such a thing exists.

But anyway, spacetime does get distorted near a black hole - e.g. time passes more slowly, from the p.o.v. of a distant observer. Between two black holes, you will see the same effects, simply due to the action of the two objects, combined.
