You'd also need the 12v starter if the car's been sitting a while - don't you need compression for this to work? I was under the impression that compression "leaks down" when an engine's been off for a while. Not an issue for idle-stop/restart, but I don't know that the Mazda approach would start a motor that's been off overnight, for example.
