I like this idea! In case you wonder where to cut the episodes, I think it should be something like this:

Lethal Alliance, chapters 1-8
The Mission, 9-12
Conspirators, 13-21
Dark Disciple, 22-25

Saving Vos Part 1, 26-28
Saving Vos Part 2, 29-30
Traitor, 31-37
The Path, 38-42

Note that the first rescue attempt has to be in the first set of episodes since there are animatics of it and no animatics where made for the final production season where the second set of episodes are from. Concept art also helps with nailing down the first four episodes.
