I disagree. It would have made sense, and it could have been done.
The #1 problem with the PT was the decision to focus so heavily on Anakin. It should have focused on Obi-Wan as the primary protagonist. And I think, had this been done, it could have worked while still keeping the surprises of the OT.
But that doesn't matter for this topic - this is about working with what we have, not creating something that was never there.
