Rule-wise, I'm not sure how they even rationalized the Multilaunch in the first place. As it says, Arsenal pg 135, the Multilaunch requires a body of 10 to install, the Large Drone Rack requires Body of 15, Small requires Body 10, and Mini requires Body of 4.
Using the pre-existing Rack, you could cause a fair bit of chaos. To understand exactly what you're thinking, I'd have to know more about the loadout of these Drones - on their own, they have zero offensive and defensive capabilities, not even the iBall's smoke generating effect.
