I don't think it is impossible, but it will still be quite a bit of work. You would have to distill all the Marlin settings and customizations from the source for the Marlin firmware used for the UM3, and port those over to the new marlin version.
You can find the source of the current UM3 Marlin here:

I don't think it is impossible, but it will be a lot of work and you will loose some functionality (such as automatic filament detection, printcore detection, the Digital Factory). Other functionality you will likely have to reimplement from scratch (tool changing, nozzle offset calibration, material changing).

Is there a possibility to change the marlin firmware to have all the current upgrades that are included now that are like the ones in Klipper? I hear the newest version has linear advance and input compensation.
