Make a 'box' that looks like a magneto and stick the coils in that.

did it on one bike years ago, looked great, extended the wires by soldering plug wire to the leads, filling the gap with the rubber sealer they used to use for power lines, then slipped a chunk of vacuum line over the joint. Stagger the splice so don't bunch up, and position them so they 'hide' under the tank means it looks good too.
