How did Christians that had converted, such as the Scandinavians, view their pagan ancestors?

Did they still respect the old "legendary" viking kings?

Arguably, yes, since literally every bit of saga evidence we have (and all of the written mythology) is post-Christianization. There was, of course, euhemerisation of the gods into Asian or Middle Eastern heroes who had travelled west, and a sort of 'they didn't know better' attitude when it came to overtly pagan religious attitudes of saga characters, but generally they were treated just as well as contemporary figures.
