I would love to see this as well! I've always been fascinated by telemetry data -- in particular because I've always wondered just how much the vocal parts of the fandom actually reflect player's trends and choices. (I always figured that it's a very small part of players that visit forums/tumblr/reddit and an even smaller part that participate.)
I can't remember the exact source, but I remember reading somewhere that Leliana was the most popular romance in Origins...? Which, if I had just gone by the opinions I've read on the boards, I wouldn't have guessed! I just love reading/watching behind-the-scenes stuff in general -- from player statistics as well as the creative and design processes that go into determining the final decisions for the game.
Looking at information like that is just really fun for me! I think it would be wonderful if some of that data regarding player choices would be shared. It doesn't affect how I play the game (although that's not to say others might not be influenced by it), it's just something that further adds to my enjoyment of the product in the same way that the 'behind the scenes' features add to my enjoyment of DVDs.
