Re: How about a "trapped in the past/future" Trek?
A ship trapped in time would only work if they kept bouncing between eras and alternate universes, never able ti find their home time and timeline: Sliders Trek.
Sounds like Time Tunnel Trek to me.
But I think a single character out of time is more interesting, the Captain America trope.
You mean like Buck Rogers, who fell asleep in 1928, and woke up in the 25th century? Captain America didn't show up for another 12 years.

Larry: I'll take the brunette!
Curly: I'll take the Black and Tan!
