Which of these (on this list) should I choose?

I was wondering if you could help me with something. Over the last few months, I've been editing the "List of hypothetical technologies" page on Wikipedia. I am terrible at picking so I was wondering if you could choose something from the list that could fit well in Star Wars. It's ok if you pick more than one. If you don’t have the patience to read my list; that’s ok. Everything is cited if you don’t know what it is. 

 

I'm looking for something

 

-Hasn't appeared in Star Wars (as far as you know)

 

-Something that would not contradict the Force

 

-Something that would not be crazy expensive and resource consuming (I say this because many megastructures are on the list)

 

-Something that would not change EVERYTHING

 

-Something worth doing 

 

Some of them already appear in Star Wars or don't apply to that universe. Filter through them

 

Here's the link to the list

Thanks so much!!!!
