If you are talking about swaping in a higher primary resistance coil (I think Ford cars did this?) then it should work. I believe the hardest part on the ignition box is having the ignition on, but the engine not running because the ECU transistor saturates the coil current (limited by the coils primary resistance), then when the ECU senses the reluctor pass the magnetic pickup, it triggers the ECU transistor off which caused the magnetic field in the coil to colapse and induce a high voltage into the coil secondary creating the spark.
Pertronix sells a canister coil with 3.0 ohms of input resistance, which would pull less current than a stock coil with a ballast resistor.
