Two big-ip partitions sharing the same pool

Hi,  I have created a ner partition and configured a routing domain for a new vserver. Is it possible to configure a different child routing domain for the pool wich resides in a different lan from the vserver and configure the pool as local even if is already configured in another partition (same vlan of the previous pool)? I actually want to share the same nodes between two different vservers which resides in two different partitions that are separated by a firewall. I would like to keep the traffic flow inside the big-ip. Thanks in advace for any reply.
