This sounds like a very good idea... The main issue I can anticipate is designing an objective enough method of deciding whether or not a character does or doesn't have a particular quality (privilege being a very good example- when it comes to Strange he's about as textbook privileged as you can get without being literal nobility, but a lot of other characters- in any fandom- are less clear cut)... A general consensus seems to be the best way to do it, at least for now.
... I may be getting far too into this.
