You can't just toss stuff at a Lagrangian point and have it stick. Getting it to stay there is much like getting something to remain in orbit: You approach hyperbolically, then you have to brake into orbit.
Yahbut...

As the debris from the Mars-sized impactor coalaced, it likely formed several moons.
The debris might not approach the lagrange points as a mass--in other words, the collisions would come from all directions. Opposing debris is the braking mechanism. All other things being equal, the most stable collection points are the lagrange points. There's your moons. In theory.
