I would love these sorts of radio dramas to see a comeback. Like something set in the Expanse universe, adapted as a podcast drama.
Alternatively, I think there's also potential in directly parodying the sci-fi of the 50s and 60s. It could be really clever if done right.
Or! You could do a weird straight-ahead period sci-fi space opera. Quality drama, but set in the goofy 60s ideas of future space travel. Think Mad Men on Mars?
