About your poll for kiis variations: why not Rozenguns? I think it rolls better on the mouth !!
Rozen is a variation from Rosen, which I think is used in Germany as a surname that comes from the german word for roses (Rose).
I think in Old English Rosen may also mean "of roses" or "consisting/made of roses".
It's really cute, and we won't get confused with the other ship that's already called Guns n' roses or summ like that !!
