I’m morbidly curious to see what would happen. Obviously I know it wouldn’t magically turn the Wii into a Wii U as it’s a totally different console - but what would it do? Assuming it could even be copied from the Wii U’s memory (and packaged into a WAD file or directly exported into a Wii’s NAND) Would it brick or freeze the system, reboot it or maybe pop up some sort of error window due to it being made with a different firmware than what a real, up-to-date Wii would be running on?
