Breaking a postulate
If you answer 20 million light years, it seems you have broken one of the postulates of relativity, ie c = 1 The interval of time described by the light clocks no longer is invariant, or constant. Instead of each light clock defining an interval of time of 1 million light years, they now describe an interval of time of 2 million years

You're not breaking a postulate, you're breaking your clocks. If you are going to use your clocks as a standard, then you cannot let the mirrors move apart with the expansion of space.
