That seems like an interesting movie. I think that Hook would have been victorius if he did one of two things. He could have not taken the kids and focus on his piracy success; but no, he was obsessed and could not let that go.
The second option? Take Pan on his offer. Leave immediately. And wait. Then he can just go back on his word and return anyway. A little deception can go a long way. Or Hell, just pay someone else to off him while Hook watches.
