How about something less blatantly rip-off-y but still pretty much based on the same premise:
Maybe there could be a religion-like Transhumanist movement that is considered too radical and unethical by everyone else and is heavy with AIs and augmentations. Something that aims to reach the "Singularity" that will lead Humanity to its next incarnation, or something equally cyberpunky. They could even have a unique culture. However I'm not really sure about what technology level this setting has, so I can't tell if they would fit on Mars.
That actually could be a great counterpoint to the UN's Humanism. While they try and keep the Human race alive and in check 'morally', this other movement pops up saying that modifying yourself with machinery is just the next step in evolution. About the whole Lojban issue, I'll have to do some more research into it and the Eastern religions.
