I've been thinking the same thing. I was hoping there would be something like this laid out in a FAQ on this site or somewhere else. I've not seen a collation or even a colloqium and I've been thinking about a way to go through all the posts in a reasonable way to collate the suggestions.
Such a grand framework is implied, but I've not seen one laid out. Most treatments of a subject recapitulatate the history of the science. Here is a great
map. There is a Philology based upon the
Dewey Decimal System which would be the place to start as a framework to enumerate the books which would form the basis of a broad curriculum. However, you would need a seperate framework for Ideas. In addition, there are methods and strategies for teaching and for dealing with issues which would have to have a framework as well.

DDC
Worst case, if you read the top two books ( most checked out ) in each section in the third summary of the DDC
( the thousands ) then you would have a very broad education.
Then use the very narrow curriculum from a major HS publisher for specific subjects required for college entrance.
