Hmm, exactly what problems do you see? That they need to be *big* is obvious, you need space for a lot of frozen people, livestock and gametes, equipment for colonization (you have to be prepared for almost anything; most likely a portable asteroid factory would be a good idea), space for thawed people to work, protection against relativistic shrapnel and of course things like propulsion, shuttles and life support.

In my scenario nanotech is assumed to be harder than we currently think (for some reason), it has taken much longer to reach than expected and the simple nanotech is still rather limited. On the other hand, fusion power got cheap surprisingly fast (it is one reason for the presence in space, the hunt for He3).

Yes, but it is fun. Wait till you see my *other* roleplaying project! :-)
