This has been tested by another on our forum, and he did see an increase in bumping the ignition voltage back up to ~14V. I do have an idea for doing this, I just haven't done it yet.
Here is his thread:

Also I have an issue with your kill switch.. the crankshaft position sensor is the most delicate noise-prone and critical line you could have chosen to introduce trouble into. The switch's presence in the circuit could easily be a source of misfire issues, plus throw the ECU into odd limp-home operating modes. I would suggest the fuel pump or ignition circuit sources for this venture, but ultimately my suggestion to someone willing to do this sort of stuff is to install megasquirt.. this will open up a whole new world of knobs to tweak, plus let you do all of these things through a laptop instead of hacks.

I am still thinking how I'll revamp the kill switch. Killing the ignition is a good idea. However, for now it is working fine. It immediately goes back into closed loop when I restart the engine.
