Can you imagine Star Trek as a Western? It's not that hard. The original series had "Spectre of the Gun," which directly referenced the shootout at the O.K. Corral. The Next Generation had "A Fistful of Datas", one of the more forgetable malfunctioning holodeck episodes. The time travel episode "Time's Arrow" is arguably a Western.
This Starfleet science division (hence the blue) officer would fit right in at a Ten Forward set in Dodge City. Miss Molly Heart wears the fetching outfit for @StarfleetCosplay.
