We have a policy set up for names over here. If you'd like to amend it, I'd recommend setting up a thread in the forums for further discussion.

Regarding the names you mentioned, a good number of the characters in the first few parts are not spelt like their references. For example, Wamuu could be spelt Whamu or Wamu, or any similar combination, but not Wham; there is an intentional "u" that Araki added in the Japanese katakana. Similar cases include Straizo, Tonpetty, Wang Chan, Zeppeli, etc. Point being, it doesn't necessarily have to be the exact same as the band name. Cars would be a viable option though, if not for the aforementioned policy.
