Was thinking about your model for redshifting-blueshifting while camping this weekend and had some thoughts for your consideration. If you do write a paper, I think it would be very helpful for you to include some graphic illustrations. It would help me (and others) follow your train of thought. Your model explains why redshifting is observed of external galaxies, but it also needs to include an explanation of why the Andromeda galaxy is blueshifted. As I understand your model, any light source arriving from space would show redshifting as it encounters the less aether-dense atmosphere around the earth.
Figure 1. Wave lengths are blueshifted (shortened) in the direction of motion and redshifted (lengthened) in the opposite direction (from http://bork.hampshire.edu/~sam/extraordinary/HDF.htm). Here is another good demo of red and blue shifts.
