I great idea with this is browder and Black are not so old it would feel weird to see them again and the puppets of course never age. I do think you would proably want to base any new show on there grownup child. Also you could really expand the sets and make the ship look even more impressive. I do think you would proably want to add another character,maybe female and potential love intrest, to show to sort of capture he romance Criighton and Aeron had. Plus I think you still would need that contemporary earth perspective for the show which you would get from the new female character.
