Well, no. ...I'm not the maternal type and have limited patience with kids.
It wouldn't be fair of me to sign myself up as a permanent member of a
family with this attitude. He and his family would deserve someone who could be totally dedicated to ALL of them. Instead, I'd end up resentful and probably would be emotionally neglectful of the kids.
If it were a question of dating a person who's divorced (but no kids), it would depend on the circumstances behind the divorce. I think a divorce can make some more mature and commited to handling their next relationship ...and then others will learn little or nothing; merely sucking you into their world of communication and personality problems, etc. It depends on the person.
