One approach would be to reuse the existing ontology framework (and 
perhaps include a NCBI-taxonomy-specific "view" to recapitulate the 
existing taxon tables).  This would have the added advantage of allowing 
DAG-like taxonomies.  "taxon_id" foreign keys would then instead be 
"term_id" (too bad there's no such thing as column-level aliases/views).
