Anniken

This name is fine (and very nice, I will add). It’s pronounced AUH-niken, anyway, so I don’t see the problem with it being confused with AN-ni-ken, especially if you’re only hearing the name. Spelling-wise, maybe, but it’s still distinct enough from Anakin to be its own thing.

I think a bad thing about this name that it is similar to 'Anakin' from the Star Wars movies, but I think it can go good for a woman of any age and it's a great diminutive of Anna too!

Sounds masculine to me because of the name Anakin, and also sounds very outdated.

Well, can you see an 80 year old Brittany, Tiffany, Katie, or Jessica, either? Those names will be considered "old" one day. I think this name is strong, but unfortunately, it will always be associated with Star Wars.

This is such a cute name! The only problem is that I don't think 'Anniken' ages very well. It's cute on a kid, and nice on a teen, and not too bad on a young adult, but can you really see an 80 year old Anniken? Maybe for a middle name it would be better.
