Hello,

I would start with an INIT program where you only have THRU algorithms. Connect each Tone X pedal to a separate insert. In the Routing menu, creating a parallel signal flow and place Insert 1 on one side and insert 2 on the other. Blend the signal of both to taste. Once you got your amp tone dialed in, you may introduce presets at the very end of the signal chain for mono or stereo audio.

You could even process each amp individually with its own effect if you wanted to.
