If this is a domain member, then ONLY the domain users will be allowed
access to the shares.

The only thing that I think that might work is not just one
smb.conf, but double everything (except nmbd), one joined to the
domain and one not.

I personally wouldn't do anything like this, it is fraught with
potential problems and dangers.

Whilst you do not want to put your local users into AD, this might be
your easiest and best way out of your problem. Create an AD group and
add all your 'local unix users' to this group, then only allow access
to the Samba shares to members of this group.
