Not going to happen without a lot of work. And by that I mean a lot of lawyer work. From what I understand, when the original contract with Fox was signed, there was a stipulation that no new episodes could be made for any other network for 10 years. We've still got a few years before they'll release it for episodes. Now for other mini-movies or something, I don't know, maybe they can do something. Hell, they released a comic, so who knows.
Oh, and I believe SciFi doesn't actually have any financial power over nBSG. They pay them to show it, but nothing else. Some British company is footing the bill for most of it. I think NBC is in on the deal too, but I'm not sure exactly how.
