I like that idea of emulating the '70s sci-fi aesthetic from ANH. That'd be awesome. Less CG, more practical sets/aliens/etc.

Nice idea, but this is Star Wars and George Lucas we're talking about. No matter what they do, CGI will be the star, not the characters.
That wasn't true for The Young Indiana Jones Chronicles.
Maybe not, but Indiana Jones takes place on Earth in the early half of the 20th century, a time easily recreated for movies and TV. Star Wars, on the other hand takes place on alien worlds and in space. CGI is a necessity. An overused one, if the PT is anything to go by, but a necessity nontheless.
