You might be interested in "convolution reverbs". These reverbs
sample and model the acoustical environments of real spaces. They use
a lot of computer cpu cycles, but it's worth it. Especially in your
situation, where it looks like you are placing a single reverb over
the entire mix. Is your reverb experiment with mabye a set of $500 or
$1000 speakers and average (?) microphones going to beat the results
of the specialists? Are you guaranteed a truck won't drive by when
you are trying to capture your reverbs? Does your mobile recording
rig have outstanding digital converters?

Just some stuff to think about. Convolution reverbs are seriously
outstanding when done right.
