Help: Music Man Majesty Connectivity.

I saw that when the piezo volume is pressed down, i can split my signal to stereo.

Now, I want to split my signal to the upper switch between the magentic pickups, and the piezo pickup.

I want to split my chain so that my Line 6 G10 will be connected both to an acoustic preamp and to my Kemper so when I’m only in the piezo position only my acoustic preamp will play out, and when I’m selecting my magnetic pickups, it will play out with my Kemper. and

Now, Is this even possible?
