It might make sense by the last film?
I am a strong believer in almost writing off the PT as non existant almost... But that particular mythology and story and if you like bait from palps I liked.
Also if you take the ambiguity of Anakins immaculate conception he could well have been created by Plaguies before Palps killed him in his sleep and as his revenge against deceit.
So like you say I would not want to change the OT to fit with the PT but if I did that is the only one I would remotely consider.
