We went to the Kimmel Center last semester in acoustics class, and this is exactly what they do. They have a huge foil on top that they raise or lower depending on the size of the ensemble. Now, they also have huge empty wells on both sides of the auditorium, and if they need wider reverb they open these huge walls in the auditorium so the sound can go all around- but I'm guessing that's beyond your means.
I also like the impulse response idea, if nothing else you can learn from doing it. The only thing I can add is that if you try delaying the sound at one end of the room, you can make people feel like the sound is coming from the other end; then, maybe, they'll move towards that end and get more direct sound.

If you can (and it's a big if), try to suspend your acoustic dampening panels above the heads of people. This will have a big effect on your reverb problems without disrupting the space in the hallway.
I like the suggestions on this thread. very insightful
