Considering that in the actual Aliens movie the dropship is launched from low orbit, a marine falling out of it and dropping on the planet should inflict some damage purely because the body would retain significant kinetic energy in addition to being heated the fuck up, if they land on something it should get owned pretty hard.
Because the bodies no longer burn up in the atmosphere and instead land on the planet (although severely damaged), they should probably gib any target smaller than the Warrior just by pure kinetic force alone.
In addition, a body crashing on Fiorina should cause a hull breach on the station and immediately depressurize it, killing everyone onboard and ending the round. I think this is an important step towards realism and CM deserves better than lackluster proto-“rods from god” orbital marine strike tactics we have today.
