Thanks.

The general idea was that the two new characters would be the Rosencrantz & Guildenstern of the PT.

They would have a small cameo scene in each film reflecting the situation that the whole order is in.

The old teacher would be killed by Vader (the final lesson, how to die) and his pupil would die deleting Dagobah from the archive records saving a certain Jedi Master.

hm, like in RotJ:R, some scenes with "normal people" (other rebels, pilots), not just our heroes, would be welcomed ...

in OT 3PO and R2 are sort of "Rosencrantz & Guildenstern", they don't distract from the main story, but have their little own adventure ;-)

why they didn't reprise this from start, is up to Lucas, who thought he needed to "explain" everything and in the end confused much ...

so maybe new extras giving insight, to what and where (the temple tour could be shown through them - but I would restrict it to just one level, maybe show council and masters in Episode1, students and other rooms in following movies) was happening, could add to the tapestry and again bridge plot holes.
