It would probably be incredibly easy to bring these features into the original game. That said I suspect that you're right and that those who haven't bought BZ for whatever reason aren't going to pushed into simply because of a few little extra features are held to ransom.

There seems to be much less interest in BZ, for a variety of reasons. They want people to buy and play BZ instead. They don't want to give them away for free. The developers withholding these new features from the original game is deliberate. I don't think adding these things would discourage people from buying Below Zero, as it has its own merit of a new story, new gameplay mechanics and features, and a new map to explore.
