I'm still not following. If the speed of light in one direction was infinite, there would not be any redshift nor any microwave background coming from that direction[0] to begin with. The photons from recombination time would have long passed us. Of course, this assumes that the universe is isotropic and what not. But again[1], the alternative would be a fine-tuning conspiracy of cosmological scale. [0]: More precisely, from the opposite direction.
