I think you can probably know more about someone by what they write than you can by knowing their name and the particulars of their life. If everyone is trying to develop a 'Voice', then, surely the voice can only be their own. Even if you mimic another, that tendency says something about you. It might be interesting to paint impressions of the fellow writers that we feel we've come to know. It could well be a dangerous endeavor too. But if you only wrote about those who were high in your esteem, then, it would limit the output to good impressions only. This is just a follow on to your idea.
