Tag /typo reviewer
a new edit role
if an edit is made that has changed only tags or that requires only tags to be checked, this could be done by this person
this person would not edit the question or answers, only the tags
I would suggest a threshold of 250 points so than more people/users would be allegeable for this
The edit queue is often full (at least on Stack Overflow), and I think that is better that users with higher reputation focus on tasks that require more attention, for example, wiki entries, edits to the questions/answers
I don't have any data to back this up. This is all based on my observations
if there is a review request that only requests to review some typos, this can be handled with someone who has a fewer number of reputation points than users who do triage/questions review
