Jovi is too Bon Jovi for me, but Jovie isn't. I only make the connection when I see it written, I've been thinking of Jovie lately and didn't even think of the connection till your post now.
I like Jovie. It's sweet and cheerful. I'd consider finding a full name, but I think to J sound is strong enough that it can also stand on its own if there's no full name you like for it. (Unlike say Ellie, or Emmy, which I find too cutesy to be full names)
Thumbs up to Jovie.
