Axiom integrated to my existing system

Hi, my system consist of a E90W with rd418hd,raystar 130,x10 pilot and anemometer and depht sounder conected to the backbone thru a itc5. My question is: if i add a axiom to my system would i be able to plug the radar directly to it and still be able to see it(the radar) thru my E90W thru the system? The reason for this is that i would like to have a extra back up screen so if my older plotter give up i still be able to navigate with the radar. If not possible what would be my option in order to get the same radar on 2 different screens?

Thanks
