Hi Melissa,
Adobe Analytics does not auto-provide this information, but if you can manually surface it to be passed into Adobe Analytics calls it looks like a good use case for Custom Traffic Variables (s.props) tracking. You then could use classifications (perhaps even Auto Classifications) to group and slice your content by the various readability data points. Since all the information is being passed in the same page image request you also have full correlation to breakdown using custom traffic variables.
Best,
Brian
