Yeah, perhaps. But I don't see how a brief meeting with him would sway Harry to trust Lucius more than Dumbledore. Especially since the first person he meets from the Wizarding World is Hagrid, who goes on about what a great wizard Dumbledore is. If in their talk Lucius said some things about Dumbledore, Harry might be more skeptical of him, but I dunno if such a brief meeting would make him trust Lucius more over Dumbledore, especially since he wouldn't see Lucius again until a year later.
