Regarding the Castellan (R4N) and the Abbot (B4N), Peter S. Hatch's Fantasy Grand Chess (2000) includes the Druid Army, with a Unicorn (R4FN) and a Bear (R4F). I cannot recall seeing a (B4WN) piece in any game.
Greg Strong's 16x12 variant Cataclysm (2007) includes the Tiger (R4F) and the Elephant (B4W). Also a Duke - moving three squares like a Queen. EDIT: the first "Q3 piece" here was the Maiden in R. Stephen Chafe's 38 squares variant PIRATES-HENGE-HO (1997). Jean-Louis Cazaux's 16x16 variant Terachess II (2020) has a Duchess - which is a Duke that can also jump two or three squares.
