Back on topic, ruining the surprises of later episodes is like reading a book that begins by telling you how things will end and then proceeds to tell the story as if nothing was said.

In all fairness, it is possible to do this, but it requires extreme cleverness. The TV series "Columbo" worked this way... you saw the murder take place and knew who the murderer was, then you watched Columbo solve it. But there were always surprises, and there was always the mystery of how he was going to solve the case.

To pull it off in the OT, would have required very clever writing to build a PT that preserved the surprises of the OT. I don't see how it could be possible without making a PT that predates Yoda. It would be clever to show yoda-like creatures living in the forest who annoying but who weren't Jedi, which would heighten the surprise in ESB when we learn that particular creature was a Jedi-master. You could also show the Hutt as normal people who are progressively getting bigger through success and gluttony... culminating in ROTJ where we see the Hutt have gotten way bigger than the viewer even could have imagined.
