Delete user and change Content Author Is it possible to Delete the user and keep its content as created by the one who deleted the user.

Suppose, abc is a user as content creator/editor only and have created 2 contents.  

abc got fired as editor and his boss xyz wants to delete his user account. 

xyz not only wants to delete abc but while deleting abc transfer all the content created by abc to his name, so that it'd be like created by xyz.

Drupal has only 4 options while deleting user account which doesn't satisfy this need.

If it is possible then how? please elaborate how to achieve that....
While canceling user account choose either Disable the user account and keep its content or content belong to anonymous user
