I'm not into star wars so it doesn't matter to me at all. Some people might think it's really awesome, wouldn't bother me either way. If you love it use it!
I’d try to avoid it if you have other names you are also considering. Not the worst similarity or association though, if you love Luke much more than other names.
Nope and because it’s not you it ultimately effects but the child who will spend his life hearing jokes. It really isn’t a decision that matters if you personally like Star Wars or not. You aren’t personally living Luke Walker
