The thing is: You fight the same order of elites (read: enemies in general) regardless of where you run into them, unless they changed what's seeded and what's more flexible.

I once bothered to replay a seed to confirm this by checking every available route. The fights were identical and the first elite was always nob, whether near the start or the end of the act.

So, if you want elite info in advance, you'd also have to change the way they're generated.
