The iCloud email account is tied to the iCloud account. If you want a different (new) email account you'll have to create a new iCloud account for your phone. You can, however, create an email alias to use associated with your current account (see http://support.apple.com/kb/PH2622). It will have a different email address, but will receive email to the same inbox as the current address so this may not meet your needs.
