I found myself thinking, no matter what it will never have the same 'feel' as the originals.
Then I though, hang on.. if AI is going where it looks like it's going..
Then maybe in 10,20,30 years with Text->Video AI, perfect face cloning and AI acting generation it will be possible to replicate the 80's feel.
You'd obviously need good story writers, AI probably wont be any good at that, but the look and feel, that it can do.
If you can speak to your computer and it can understand all objects and animations in a 3D scene, and it can understand what you are asking it to change, then maybe you can keep refining a scene until it has the feel you want, the simulated acting you want, and the faces you want.
