A Wild idea for Favero Assioma pedals [MTB SPD Hack]

Is it possible to just learn from Garmin Vector experience about using a cartridge kit to convert Look to Shimano petal?

If the inner diameter of selected Shimano pedal is larger than Assima pedal, then it is possible to handmade an “adapter or tube” by CNC for either metals or engineering plastics, also CFRP-made is considerable.

Personal use, no license violated issue.
