Hey, that's the project namespace, which I'm afraid can only be changed by Staff, via Special:Contact/general.

Note that there's an alternative option: you could have a namespace alias created. Several wikis have had shorter versions of their SITENAME aliased to their project namespace: for example, if you go to VA:Chat on Fallout Wiki ("The Vault"), it automatically aliases to "Fallout Wiki:Chat" without creation of a specific redirect for that page. If you had a namespace alias enabled for "CAW:" or something, that might meet your needs without changing the actual project namespace itself.
