Admins already use this tactic (sometimes) but i like to explain it more further and add some suggestions.
If a Moderator has been removed, admins must inform that moderator applies are now open, and they'll be taking 5 (or more) candidates.
Every candidate will be examined for a week, like a background check or something (maybe), if someone get's the admin's trust, he could be the server moderator.
If there is no vacancy for moderators, every applicant will be rejected automatically, and the thread will be trashed.
[just saying, i hope it could be useful]
