- one mag and one electronic.   Seems plausible but you lose timing control if you leave the mag on.    If I were going to do this I would want to run most of the time with the mag off I think.....and that would mean different timing curves.    I don't know if any of the electronic setups deal with that properly or not.
Running with the mag off could very well cause bigger problems than it solves. With a single ignition point, the flame has to travel a greater distance across the combustion chamber to complete the burn. This results in part of the fuel charge existing for a longer period of time at elevated temperature and pressure, which may very well yield detonation. Detonation can damage the engine by itself over time or  may lead to preignition which will destroy it in short order.
 
Also, from a performance stand point, you want the fuel charge to combust in the shortest time possible. You may recover some power by advancing the ignition some on one plug, but this probably won't return performance to the two plug condition.
