You know that republics and dictators aren't mutually exclusive, right?
Anyway your comparison doesn't work - dictators in the Roman Republic were appointed by the Senate for a set period, after which they were liable for close scrutiny of their actions and possibly liable for a trial with harsh punishment; your JCS scenario is a classic case of a military coup, which was definitely not the case with men such as Cincinnatus, Fabius Maximus, and other dictators, though Sulla did seize dictatorial power for himself.
