LINUX MINT DISTRO CUSTOMIZED

We need to build a custom linux starting with the Mint 20.3 Cinnamon Edition. The changes to be made are of a graphic type, the distro should assume the graphics of the Workbench AmigaOS distro (http://workbenchos.prismadigitale.it/). All the functionalities must be brought back to the Amiga operating system, moreover it is necessary to produce a work book which shows all the changes made and how to reproduce them by us.
