You don't refactor your DBMS per se., what you do is make you own custom mappings in your R2RML. Of course, if your database modelling doesn't fit your mapping requirements you will then have to massage your modelling using Views. Remember you are basically mapping relational tables to RDF statement graphs i.e., different ways of representing entity relationships.
