Nah, they can't fall. Basically the entire Underworld right now is running under the FGS and Bael Clan. In fact, like mentioned many times, the Bael Clan has more influence than the current FGS. You can say it's the same for the Agares too which ranked second among the 72 Pillars. That's how the Agares serves as the "middle-man" between the Bael and FGS.

Remember, the current Devil goverment consist of Devils that survives the Great War, they each have different views on how the Underworld should function, that's why the 4 Satans each have 4 opposing factions, if the Bael clan falls, then those Devils would start to be more extreme on their actions and just start doing what they want. So the Bael and Agares are an essential towards the current Underworld.
