Which of these (on this list) should I pick for my Star Wars story?

[Maximum7]

was wondering if anyone could help me make a decision on picking a technology for my Star Wars story. I’ve been editing the Wikipedia page “List of hypothetical technologies” for many months now. I’ve worked hard on it but I can’t pick something.

I’m looking for something that

•Would be worth creating

• Wouldn’t be easily created based on existing technology.

•Something that doesn’t already exist in Star Wars Legends or Canon.

Believe it or not, a Dyson sphere actually appeared in Star Wars. It was called Iokath and appeared in The Old Republic MMORPG

You can pick anything on the list EXCEPT “Black hole starship” , “Language learning pill” and “Artificial super mitochondria” since I workshopped those ideas and I determined they don’t work. Here’s the list
