Famously, Raiders of the Lost Ark (and indeed all of the series) have many Star Wars references as Easter Eggs, from the registration of the floatplane (OB-CPO), to the Shanghai nightspot Club Obi Wan, to the two droids appearing in a heiroglyph as per the previous link.
So it would be lovely if the five letters RD/CPO appearing together was a fun insertion, but again I think I’m probably over-Listenered in 2020...
