You can use the banshee parts if you modify everything to fit, but the question would be why? The stock system is better.
If you use the banshee parts you would not need the crank trigger unless you decide to switch to a wasted spark cdi. You wouldn't be able to use a banshee/rz cdi since the timing advance is set up for a 2 stroke. But you can use the banshee system, keep your cam trigger and use a stock tci or a pamco.
Basically, there is absolutely no point in ditching the stock system, at all. Most charging gremlins on the stock system are elsewhere down the line, either bad wire or bad connections.
