It might be better to send the lines to another processor.  It would be nice 
from a current consumption point of view to use latching relays, which means 
the set/reset pulses would work better under a second processor control.  Some 
of the PIC chips are really cheap and the processor would be doing almost 
nothing.

Use 74HC138N  3 line to 8 decoder a transistorto drive the relays ....
138 is active low outputs,  238 is active high outputs so you can 
have anything you want
