I wonder, does FFG have a LCG without that 3 cards in the middle there? Anyway, I am not that opposed to that idea, but how likely is it that they will make L5R that way?
There is some departure. Conquest has 5 worlds, for example, that you can struggle for with command icons to collect cards and currency, but you still only actually fight at 3. Likewise, Lord of the Rings does away with 3 cards in the middle in favor of 1 Quest, maybe with a Buffer location, and the staging area, but you're still choosing whether to commit each of your characters to Questing, Defense or Attack.
There's some variation, but I do hope L5R stays away from the underlying structure.
