are we talking flat into a 2D object? So the earth becomes a disc? Since they idea of density in 2D (as you're units suggest) is icky to me.. (and utterly useless for most of what I do).
If so I don't really have a clue I generally assume that the density of the galaxy is ~0 most of the time.
If you flatten i'd say since I there is a huge space between stars within out own galaxy there is probably much more space than mass. So again 0.

Anyway, I won't accept 0 as an answer as it's obviously not 0 because there is stuff. Compared to the Sun's value it's 0, I'll give you that much....
