You might want to check [X-In/1-Out Non-Mixing Extruder Config](https://klipper.discourse.group/t/x-in-1-out-non-mixing-extruder-config/2387) and [X-In/1-Out Non-Mixing Extruder - Automate SuperSlicer & PrusaSlicer Filament Swaps](https://klipper.discourse.group/t/x-in-1-out-non-mixing-extruder-automate-superslicer-prusaslicer-filament-swaps/5285/)

Apparently @jjarosz is successfully running such a setup.
