Jeff,

 

It may be worth considering connecting the coils such that opening a fuse only affects one coil of each rotor.  Loosing either the trailing or leading coils has a noticeable but minimal effect on the engine as demonstrated by executing the coil test available when running on the B controller.  That is certainly not as serious as completely loosing one of the rotors.  The wiring scheme you show makes this very easy to check out for yourself.
