I could see potentially having a version of the Wild in Bretonia, due to the research being done on captured Nomads at the Cambridge Research Station, but as far as having a seperatist or seperate version of Nomads - I don't think you could really do that due to the nature of Nomads themselves.
Beings with shared intelligences tend to not really be able to rebel - they tend to get destroyed by other members (based on other science fiction stories, anyway).
