Bobby,
Adding a CAS = controlled EDIS-4 would just be an ignition backup.

The configuration I worked out was:
-for ignition, the MegaSquirt co= ntrolled two EDIS-4.  If either EDIS-4 failed, I had backup.  If = the MS failed, the EDIS-4 would continue to run on their own in limp-home m= ode.
-for fuel, the MegaSqu= irt controlled the normal set of 4 injectors.  O2 sensor feedback help= ed to set the tuning, but mixture was controlled by manifold pressure and R= PM in normal operation.  A separate, needle-valve controlled, gravity = fed line was run to the throttle body to supply fuel in the event that the = MS or injectors failed.
