Theoretically, can you throttle more with closed cycle since the lox / methane pumps are on separate shafts / systems and maintain the proper ratios?

You can deep throttle on single shaft system by choking flow of fuel or oxygen between pump & combustion chamber. Problem is more with the tiny rocket engine that powers the pump, called a gas generator. That has to throttle *way* deeper than the main chamber.
