It’d work; I’ve thought that it might be useful for cranks, as of the cranks I’ve bent all of them have been the left side… so if I hadn’t chucked them out I would now have loads of perfectly usable right cranks. Presumably others might bend the right cranks more, so have lots of left cranks… put the two together and you’ve got another set of cranks rather than two cranks in the bin.
If someone else were to wreck right pedals, they would have loads of left pedals going unused, and so could be used by the people who need them.
