* The problem is more insidious because we are not actually dealing with complete randomization of time alignment.

Ignoring frequency, a simplified way of thinking about this is to assume that the wall has numerous identical drivers. Thus, timing from a listener's perspective becomes increasingly lagged as we move to speakers increasingly away (out/up/down) from the listener. So the "leading edge of waves" is easy to imagine transforming into a "smooth leading smear." 

In reality, what happening is that there are a limited number of drivers, each with its own spec and consequently in its own time domain. This would likely result in an even wider smear than in our simplified example. It would be also be a consistently "lumpy leading smear."

* Ignoring the time domain, adding "lots" of miscellaneous drivers is one potential way to smooth out frequency response at the micro level (although this has a similar randomization problem).

Of course combining time domain and frequency in the real world makes things a lot more complicated, fast. The wall might provide an intersting sound, but that could just be a result of lots of trial and error (law of large numbers).

Principally due to the time alignment problems, I would expect this wall to sound both sloppy and disjointed. . . but you never know!
