Yup, you can depledge and join whatever. The other group doesn't have to take you though. As a founding member, I can tell you that the rewards for doing it keep coming long after graduation. I don't know what promises you've made to this colony, but if I was in your position, I'd be concerned as to how this would reflect on my character, whether I was acting honorably, etc.

It's not the traditional experience though, and if you're looking for that and the promises you've made mean nothing to you, do what makes you happy.
