I believe that to be impossible, (as, from what you write below,
you seem also to doubt). The people going about their business
communicate, and when they speak to each other they invariably
mention their own mental states. The notion of zombie implicitly
postulates that there is no "inner experience". But look as you might,
you'll never find where the "inner experience" is inside the brain
anyway! Consciousness arises from just the processes that allow
a brain to be aware of its own signals, and to report on them to
yet other parts of the brain.
In short, I agree with Dennett, who thinks
A physicalist might respond to the zombie argument in several
ways. Most responses deny premise 2 (of Chalmers' version
above); that is, they deny that a zombie scenario is possible.
One response is to claim that the idea of qualia and related
phenomenal notions of the mind are not coherent concepts,
and the zombie scenario is therefore incoherent. Daniel Dennett
and others take this line.

Hmm. Could be, I'll have to think about it. But I think that there
are already good arguments against rainstorms and digits of pi
being conscious. The first isn't built for it, and the second doesn't
achieve information flow (i.e. is timeless).

Well, your brain and my brain can! :-)
