I think doing so would kill Drogon (we haven't seen what Night's King is TRULY capable of) and I never said it requires the extinction of House Stark what I meant is that all other houses in the North could may as well give up their lives to remaining members of House Stark while they flee south due a White Walker invasion. Because let's face it Westeros is huge and I don't think Daenerys will hop on to Drogon and FLY ALL THE WAY to the Far North just to save a relative.

As for Ghost I think you may be right - the sole surviving Direwolf could be Queen Nymeria, may she will return will a big pack of hungry direwolves (one could only hope/wish for something like that)
