Would this be the same gaming experience?

I want the other zombie maps for Call of Duty: Black Ops. I am slowly getting bored with Kino Der Toten, Five, Dead Ops Arcade, and Ascension. I heard of the other zombie maps being on the Hardened and Prestige editions of Black Ops, but I have already gotten the original game and refuse to spend $150.00 to get the now scarce Prestige. I was wondering if I could get Call of Duty: World At War and then get the zombie maps that I don't have off the Playstation Network. Would It be the same as zombies on Black Ops?
