And this one you need to expand on " and we would also expect that the CMB radiation would be relatively uniform in temperature. " I guess you consider it following from your first statement?It does not follow from the first statement, it follows from that fact that the speed of light changes.
If, in the past, the speed of light were greater than it is today, then we would expect that two objects (or sections of fluid, or whatever) would be able to influence each other from farther away than is possible in a constant-c universe. If the speed of light were great enough, then that would mean that every part of the universe was interacting with every other part of the universe almost instantaneously. You didn't have to wait 20 minutes for infrared waves to travel 20 light-minutes, it was much quicker.
This would mean that at that time, the temperature of the entire universe would approach equilibrium much faster in a slowing-c universe than in a constant-c universe.
This would mean that the CMB radiation would be more uniform in temperature in a slowing-c universe than it would be in a constant-c universe.
The discussion would change from "why is the CMB so uniform?", to "why is the CMB so ununiform?"
There are several difficulties with that idea Cowlinator. One main come from how a 'Big Bang' is presumed to act. A inflation without a 'center' is not something that need to relate to the geometry we define, and a 'lightspeed' would not be acting the way one might expect there. There is no problem in letting 'c' be 'c' for it to connect 'nodes'. And the 'nodes' making this universe exist is defined by 'c'. You could just as easily imagine a Big Bang to be what creates the connections allowing us a universe to define. It's very hard discussing a 'small universe' inflating unless one step away from how a 'Big Bang' is thought to act in mainstream physics.
"The CMB radiation would be more uniform in temperature in a slowing-c universe than it would be in a constant-c universe."
is true in an universe with or without inflation, and is also true in a universe with or without a big bang.
