Obviously you’re a long way off even thinking about it, but would you consider tackling Rebels in a similar way? It’s a far more episodic show, not really structured into arcs, so it might be tougher to whittle it down.
I agree that anything that makes TCW feel less obviously like it had no idea where it was going until Season 3 or 4 would be a good idea (on the condition that it’s executed reasonably well).
