I would find some intelligent coils that do not need an ignition amplifier (Less to go wrong and much tidier wiring) make a new subloom for coils using +12 from a nice new relay with a 15A fused feed from the battery and the coil of the relay ignition switched. Ground all the coils locally at the engine and run 6 new trigger wires from the ECU. You will switch the ignition mode to direct spark  (as long as you have enough triggering - crank and cam sensor) and set the correct spark edge and dwell settings.

LS coils do not require an external ignitor.

 

If you have 6 ignition outputs that you can use, then it will be easy to change, just wire trigger direct to relevant pin on the coil as per above ( and configure ecu accordingly )
