Yeah, that's definitely an interesting question. For northbound/eastbound Exo departures, I figure that passengers will be fairly spread-out among different REM trains as people won't all aim to arrive at the station exactly the same number of minutes before scheduled departure. The big question, like @andrewmaps said, is the westbound/southbound transfer.^^^The question is (as @andrewmaps said), how many REM trains will it to take to absorb all the people on a Mascouche Line train? I could see it easily taking 5 or more REM trains. Don't forget the REM trains won't be empty when they arrive at Côte-de-Liesse.
The good news is that since that transfer is not cross-platform, passengers will be somewhat spread-out by the train doors and station stairways, since people will take different amounts of time to exit the train, and different amounts of time to reach a stairwell. With REM service every 2.5 minutes, the passengers probably wouldn't all arrive at the REM platform in advance of the same REM train. But I doubt the spread would be more than 3 trains.
I expect that the Exo trains will be smaller than they used to be, given that the transfer will indeed dissuade some ridership compared to the old fast and direct route (though it's still better than a 36-minute detour around the mountain). The old train sizes also included space for people from Canora and Mont-Royal stations, who no longer need to ride Exo at all.
