On the Celebration Day (Led Zeppelin) DVD package, the bonus DVD is a live run-through of the entire set, filmed, including some of the banter from Robert. The actual show is a little different; the banter is mainly the same, but a couple of the songs - 2 or 3 - have extended solos. But they were able to sort of "map out" where the set was going and how long it would take to get there.
If my memory serves, there is a video of a similar thing in one of the Genesis box sets; I want to say it's the third one (the Genesis - 1983-1998 set) from the Mama tour, but don't quote me on that. It's not complete, but it's the same idea, and you have the pauses for Phil's crowd interaction (I don't remember if he actually does it or not).
Look, there are better musicians on this board than me, but in my time in bands, this isn't really rocket science. The only real risk - which I imagine DT is immune to because of their age, experience, and the click set up - is that when on stage, the tempos increase and the band races through the sets (I think this was always a thing with early Maiden with Clive Burr).
