True, Freefall couldn't just be made into a movie as is. However...
The Marvel Cinematic Universe has been doing well by cherry picking characters and situations and rewriting the basic story into something coherent. The first (and best) of the X-men movies combined original X-men with New X-men in a new story.
The Tintin movie took elements of three different graphic novels and added new stuff to get a coherent movie.
I think that there's lots in Freefall that could be woven into a great movie. The gradual build up, the humor, Florence getting kidnapped to the secret arctic lair, the race to stop GitD. All that's needed is someone who could take all the threads and reweave them.
