That was the idea that was going through my head, sadly though this wouldn't be "ease of use" friendly due to players needing to bring out their ghost in potential firefight scenarios. Players that have no issue interacting with their ghost on the fly won't face this problem, but newer players that are new to shooters will take issue with a control scheme that requires you to bring up a menu to activate a flashlight mid fight if you need it. Overall though its a valid idea. Not optimal, but valid.
