Another DS9 prompt if I can. What about race swap? Like Churian Bashir is a cardassian doctor who was left on Terok Nor and now working in medbay bcause lack of Starfleet medical personnel and Elim Garak is a human tailor crafting all those bright outfits for both Siskos, who arrived on this stations to see new fashion from the farther corners of Alpha-Quadrant.
Ooohh, sounds interesting! And Garak is also a runaway section 31 member in hiding or something
