You could do this by placing expansion boards in the valve boxes, they would of course have to be sealed for water intrusion. You may have to boost the signal on the wire as well which would require a bit of electronics knowledge.

The problem you will need to overcome for a bus system is a processor on the valve end to receive the signal and open the correct valve.
