Not something I am that familiar with but I think you may need to think a bit further. With an ignition coil the induced voltage is proportional to the rate of change of current so having resistors in the circuit will be against the efficiency of the original circuit. The flywheel magneto type ignition provides a very rapid rise time and high voltage discharge which fires the mixture efficiently. A totally electronic system such as you imply can do the same but your solution, I don't think, would be very efficient. Slow risetime could result in a weak spark. From what I know the first system you mention(battery and coil) would be perhaps easier to handle but an expert would probably be able to give more guidance. Have you tried a motorcycle forum?
A point to mention is - Do you have a faulty condensor which is resulting in rapid burning of the points?
Another point to mention is that it is sometimes possible to convert 6V systems to 12V. I have come across someone who did that with an old 6V Honda 175cc then fitting 12V ignition / coils but obviously this was battery and coil in the first place. The alternator coils just give an unregulated voltage.
