I feel like I've seen GBIC sleeves that accept SFP modules very similar to QSFP+ CVRs, but I can't seem to find any evidence of these ever existing, so perhaps I'm misremembering.

It might not actually be compliant with the specs (the document I found only lists SC fiber or copper (coax with BNC, TNC or DB-9?!)), but that doesn't mean that no-one made them.
