I think you can do that if you configure the dhcp servers as
non-authoritative and do not permit both to answer unknown
MAC addresses but I've forgotten the details.  The other
simple-minded way would be to run the staff dhcp server on
a different port and require custom boot floppies to access
that server.

If your fiber-capable switches have management/vlan capability you
can easily make it look like you have two physical subnets with
a single connection between switches.  This would be the best
approach if you are trying to isolate usage for security reasons.
