They try to make rules to make it simpler. It just does not work out that way.
I expect the couplers won't work for the rear brake.
I really wanted to make the same situation work with Di2 since I have an internally routed rear brake cable. Best I could come up with is solder the rear brake cable end so you can fish it through without fraying it. It won't be that fast a swap. If you've got externally routed cable, so much easier. You could even take both brakes with housing off the bike and swap the whole assembly.
