I will be extremely impressed if the team can achieve this dialogue change given the lack of resource material. However, if it doesn't seem possible to make it work to Ady's standards, I don't think anyone should consider it a deal-breaker. After all, yoda1138's logic makes a lot of sense. If Palps was all-knowing, couldn't many of the saga's events have been avoided? I like how at that point he's still kind of in the dark (pun intended) about the threat of another Skywalker. The change would be neat from a purist's perspective, but not being able to make it work wouldn't compromise the story, IMHO.
