"on-topic" ?

Are you suggesting that our elaborate speculations for improving BBDs are
*not* on topic?

Anyway, one of my initial thoughts was that any errors in the compansion
might be exaggerated in some ways by the frequency expansion stage, but
having a narrow band signal going into the compander should help to keep
those errors to a minimum in the first place. I'm just having trouble
imagining why a compander, properly tuned for the signals passing through
it, would have a negative effect on the transient response.

Perhaps it's primarily the band-splitting that worries you? Perhaps you
think that the transients would be hard to reconstruct from multiple
bandwidth-limited sources?

In the end, all of this speculation *really is* like creating "peas on a
cob". It's a lot of effort to achieve something than can easily be done
through simpler means--in this case digitally. However, where's the
"Twilight Zone"/"Mad Scientist" DIY fun in that?  :)

Here's a scary thought for you:   Somewhere, there is probably a mad
geneticist that is secretly perfecting "peas-on-a-cob", as we speak.
