I'm afraid not, no. You could use the ON UNBAN event to re-ban every address that is unbanned (edit: shown above

), but I don't get the point of opping people when you don't want them to be able to have the access that ops have?
I suggest you set out rules for your ops, then op the people you trust to follow your rules. If you don't trust them they shouldn't be opped.
