Remember that the movie is Togashi "prototype" of York New so I'm not doubting the Idea.

but in terms of the canon timeline then my answer is NO.

Who knows, maybe Shal was a runaway that had an abusive/disfunctional family. He probably wanted nothing to do with them and Chrollo might have talked him into becoming a Troupe member with his "charisma". I sense a Sensui and Game Master flashback from Yu Yu Hakusho coming up. If you seen it you'll know that Chrollo would be Sensui and Shalnark would be Game Master.
