I have no idea. The OE ignition system is engineered with specific coil resistance, wire resistance, non-resistor spark plugs, and shielding (the metal boot covers that contact the head casting) to create a proper voltage wave form/spark characteristics while meeting EMI requirements.

Change one thing and you may have a problem Change two things and you'll probably definitely have a problem.

If you're a EE with experience in ignition systems, feel free to re-engineer the system. If not, I would recommend sticking with OE or OE equivalent components.
