What about place for optional 2 x RJ45 connectors? For Model Railroading, NMRA (the powerful US Model Railroading Association) is setting NMRAnet features for a standardized bus based on a CAN-bus with OpenLCB protocols and specs, including 2 RJ45 connectors in each board.
But main feature to be incorporated, as you pointed before, should be the possibility to piggiback on an Arduino two or more Shields using SPI transmission (that is, your CAN Shield plus another other shield), thus allowing Arduino to have two different SS pins to able / dissable one or the other shield according to which one should communicate with Arduino at a due moment.
