Dual SBS Servers on a Network?

We currently have one SBS server running on our network in the local IP range of 192.168.30.x with the 255.255.255.0 sub. I would like to configure a second SBS server, although Microsoft does not allow the operation of two SBS servers on the same network. If I use a different Local address set with the same subnet am I considered to be using a different network?

All help is Appreciated.

Thanks
