Koa full name

I love the nn [name_u]Koa[/name_u] for a boy and I also have the nn [name_u]Kai[/name_u] for a boy or girl as well and I think it would be cute if they were twins
For a boy I have [name_m]Malachi[/name_m]/ [name_m]Malakai[/name_m]- nn [name_u]Kai[/name_u]
For a girl I have [name_f]Kailani[/name_f]- nn [name_u]Kai[/name_u]

And then I love [name_u]Dakota[/name_u]-nn [name_u]Koa[/name_u] but where I live I can only use it as a girls name so I am looking for a boys name that is long and could have [name_u]Koa[/name_u] as a nn

Some ideas I have (some more of a stretch than others):

Kekoa
[name_u]Kainoa[/name_u]
[name_m]Jacoby[/name_m]/Jakoby or [name_m]Jacob[/name_m]/Jakob
[name_u]Kodiak[/name_u]
[name_u]Kolby[/name_u]
[name_m]Nicholas[/name_m]/Nikolas
[name_u]Rocco[/name_u]
[name_m]Nakoa[/name_m]

However, I think [name_u]Koa[/name_u] is best standalone. I think you could totally have a [name_u]Kai[/name_u] and [name_u]Koa[/name_u], with [name_u]Kai[/name_u] being short for something and [name_u]Koa[/name_u] being standalone.

Jakob
[name_m]Konrad[/name_m]
Konray
[name_m]Kristopher[/name_m]
[name_u]Kodiak[/name_u]

I agree about [name_u]Kolby[/name_u]/Koby nn [name_u]Koa[/name_u]!
I also like [name_u]Koa[/name_u] as a stand alone name

Kody, [name_m]Koen[/name_m], [name_m]Kole[/name_m], [name_m]Kolton[/name_m], [name_f]Kosta[/name_f], Konstantine, [name_u]Korbin[/name_u], [name_u]Korey[/name_u]
I personally love [name_m]Koen[/name_m]

Maybe [name_m]Koray[/name_m]?
