I'm certainly not opposed to this, but wouldn't a "suggested revisions" option be more suitable? I could see users quarreling over appropriate article names, and perfectly valid ones being changed without need. For instance, a user could suggest a grammatical revision, and in a small space beneath the title, people could vote on whether or not the revision should supersede the original. A certain set threshold would allow for this. Of course, these changes would also be subject to moderation.
