Ok, you sound like you know what you are talking about!
I do agree that the back looks pretty good, the sides curve in nicely. the back window also does not accumulate a lot of snow, it does some what but that is part of having a back window.
I think that you are correct that is not worth the risk of making it worse, a Kammback would have to to have the same shape in the front as the boat tail, not worth the risk/ hassle.
other mods that might help?
would wheel skirts help?
