Interesting question (since I had the same thoughts some year ago :) ) Anyway, those thoughts is what became the main motivation for the RDFIO extension [1], namely to allow import of "individuals" and exporting again using the same URI:s/vocabulary. RDFIO only supports general RDF triples at the moment though, but should be extendable to extend to support OWL too for the one who has the time ... :-o RDFIO uses an own "Original URI" property (mostly in order not to clash with existing import functionality), which can be used in the SPARQL endpoint to convert from SMW:s internal URI:s to the "original URI:s" again, in the query results, by checking a checkbox (can be tested live here: [2]). The (ARC2 powered [3]) SPARQL endpoint supports the CONSTRUCT keyword, and so can be used to make RDF exports. I'm sure far from everything is perfectly thought out in RDFIO, but maybe it can be a useful starting point work for similar things like this.
