I don't think you can do all of that with just 1 instance of sshd.
You can, however, have more than one instance running, and use
iptables to redirect the connections based on the source IP address to
the correct instance (each one with a different port and config file).

Since sshd's footprint is very small, that should have no nasty
side effects.
