There are multiple national organizations which already are everything you've described to us so far. Why are those groups insufficient to meet your needs? I can tell you from experience, even starting a colony of a major national fraternity with all of the support you get, the advice, built in alumni support, etc., is not easy at all. What you're proposing is on the ragged edge of impossible (but it obviously has been done, hence the existing LGBT groups). So why do you want to reinvent the wheel here?
