Well you could conceivably do that, but it will be very disjointed and jarring for the story itself.
Because there is no "rest" between them. It was one of the things Berenger/Vincto pointed out to me and why he disliked ending a module at the end of the dungeon crawl. Doing that without the proper "feel" of a resting or calm before the storm, makes them feel very jarring. Which is why I changed tactics at the end of In Pursuit of the Slave Lords and now in Moathouse on the Borderlands.
If you noticed in the end of In Pursuit of the Slave Lords its the only module of the series that you come out of the cave at the end to receive a proper epilogue or closing of the story, and its been a much more comfortable ending for people.. I've started to realize the importance of that rather than just cutting it off abruptly and just moving on to the next one.
