Erik,
I think your next stop would be a programable ignition only ECU like the Haltech VMS that would allow you to map ignition timing against engine load and then use this ECU to trigger the CDI unit.
More on the Haltech VMS here:

However given the cost on such a unit, you would be tempted to bin your old K Jetronic fuel system as well and go to a full EFI ECU that controls everything easily and seamlessly like a modern car.
