What do you think of these unusual baby names?

i like 'weird' sort of names, definately not traditional. We have a son called kyuss (ky - like kylie and then uss like kiss). we have a 2nd on the way now and we have just been throwing a few names around. what do you think of, for a girl - poppie and pheobe, for a boy - onyx and kobe (like globe but with a k). also would it be ok to have 2 boys with the letter k?
