More as a curiosity than something I’d actually want to see/hear, I wonder what sort of things could be done to the OT’s dialogue to better mesh with the prequels.

A few things come to mind:

Changing Obi-Wan’s line to “[I] wanted you to have this when you were old enough, but your uncle wouldn’t allow it.”
“…[a] Jedi Master who instructed me.”

I wonder what other subtle tweaks one could implement. Don’t worry, I’m not thinking of doing anything like this for this project!
