MediaWiki (the software running wikipedia) has this queuing feature already, it's called pending changes (edits from IPs/new users require review before going live): https://en.wikipedia.org/wiki/Wikipedia:Pending_changes

It is often used in non-english Wikipedias as default for all articles, on enwiki however only a very limited number of articles are protected in this way.

However review guidelines usually don't ask for a check of correctness, but against spam and other obviously inappropriate content.
