[Opinions] That's really cool!
It's sounds German, anyway...especially considering how you pronounce it.
A few months ago I encountered a child Jacoba in the newspaper...it made me so happy to see that. I first saw the name in 8th grade...apparently it was a name most commonly used among some Scandinavian monarchy in the 17th century...I always liked it more than Jacob, but now I like both just as much.
Jacobine, especially with the German pronunciation, tops them both.
