That is because it has been impossible to measure OWLS from a moving 
source. The best that can be done even now is a comparison of two light 
speeds and that too is still very difficult because of extinction and 
unification. The only moving sources worth investigating are orbiting 
stars...and they show quite conclusively that their light INITIALLY 
moves at c+v towards Earth.

I don't wish to get anything 'right' in your fantasy universe.
I'm only concerned with the real world.
