Once again bailed out by a comment from @AKSW, who doesn't seem to be especially obsessed with earning reputation points.

This CONSTRUCT, with an embedded SELECT, gets all triples from my model, depleted of any triples in the MINUS block, even when they contain variables. I'm pretty sure I can flesh out the MINUS block and finish my task.

PREFIX  rdf:  
CONSTRUCT 
  { 
    ?s ?p ?o .
  }
WHERE
  { SELECT  ?s ?p ?o
    WHERE
      { { ?s  ?p  ?o }
        MINUS
          { ?s  rdf:type  ?o }
      }
  }
